Lowest Common Multiple?
816611
hi,\n  regarding lcm of a set of numbers.....\n\n  the lowest common multiple (lcm) of two whole numbers\n  is the smallest whole number which is a multiple of both.\n\n  consider the numbers 12 and 15-----\n  the multiples of 12 are : 12, 24, 36, 48, 60, 72, 84, ....\n  the multiples of 15 are : 15, 30, 45, 60, 75, 90, ....\n\n  60 is a common multiple (a multiple of both 12 and 15),  \n  and there are no lower common multiples.\n\n  therefore, the lowest common multiple of 12 and 15 is \n  60.\n\n  now try it yourself for 120 and 130.

Find the lowest common denominator.\nThe lowest common denominator is 20.\n\nAdd the increment hours together.\n5 plus 4 is 9.\n\nDivide the lowest common denominator by the increments.\n20 divided by 9 is 2.22222.\n\nSo the answer is 2.22222 hours.

Assuming that the two numbers are positive, the best you can do is take double and triple 850.  Both numbers will be divisible by 850, and since neither can be divisible by the other they need each to be multiplied by numbers which are not divisible by the other.  The smallest numbers that work are 2 and 3, so 850 * 2 and 850 * 3 are the smallest solutions to your problem.

To find the greatest common FACTOR, here is an example:\n\nFind the GCF of 36 and 54.\n\n    The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.\n\n    The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.\n\n    The common factors of 36 and 54 are 1, 2, 3, 6, 9, 18\n\nAlthough the numbers in bold are all common factors of both 36 and 54, 18 is the greatest common factor.\n\nThe second method for finding the greatest common factor is to list the prime factors, then multiply the common prime factors. \n\n**************************************\nTo find the least common denominator:\n**************************************\n\nTo find the least common denominator, simply  list the multiples of each denominator (multiply by 2, 3, 4, etc.) then look for the  smallest number that appears in each list.\n\n    Example: Suppose we wanted to add 1/5 + 1/6 + 1/15. We would find the least common denominator as follows...\n\n        *\n\n          First we list the multiples of each denominator. \n\n        Multiples of 5 are 10, 15, 20, 25, 30, 35, 40,...\n\n        Multiples of 6 are 12, 18, 24, 30, 36, 42, 48,...\n\n        Multiples of 15 are 30, 45, 60, 75, 90,.... \n\n        *\n\n          Now, when you look at the list of multiples, you can see that 30 is the smallest number that appears in each list.\n\n        *\n\n          Therefore, the least common denominator of 1/5, 1/6 and 1/15 is 30.\n\nThis method works pretty good. But, adding fractions with larger numbers in the denominators it can get pretty messy.\n\nSo hold that thought for a moment, as we look at another way to find a least common denominator for adding these same fractions.

Multiplying the denominators of all the fractions would be the easiest method.\n\nHowever, if the numbers are really big and you prefer working with small ones (e.g. if you do not have a calculator), you can first find the lowest common multiple (LCM).

Perform a prime factorization of each number:\n16 = 2 x 2 x 2 x 2\n36 = 2 x 2 x 3 x 3\n\nTo find the lowest common multiple, you need to take each prime factor, enough to cover both numbers.  In other words you need four of the 2s and two of the 3s.\n\nLCM(16, 36) = 2 x 2 x 2 x 2 x 3 x 3\nLCM(16, 36) = 144\n\nThe other people might be thinking greatest common factor, but even that answer is wrong since the GCF(16, 36) is 4, not 2.

You want the greatest common factor (not the lowest common multiple) to be 42... A few other answerers are giving you numbers that would be have 42 as their LCM, not GCF.\n\nSo just multiply 42 by a couple of numbers that are relatively prime.\n\n(Numbers that are "relatively prime" have no prime factors in common.)\n\nFor example 42 x 2 and 42 x 3\nor 42 x 6 and 42 x 35\nor 42 x 7 and 42 x 18\netc.\n\nThe easiest case would be 42 x 1 and 42 x 2\nGCF (42, 84) = 42\n\nBut other choices include 42 x 2 and 42 x 3:\nGCF (84, 126)\n\n42 x 10 and 42 x 3\nGCF (420, 126)\n\netc.\n\nThere is no single answer to this problem, but there are wrong answers.  :)

7,200 is the correct answer.  This is the least common multiple of 45 and 800.\n\n5 is the greatest common divisor of 45 and 800, not the least common multiple.

I just plugged this into my calculator.\n\n[1, 0, 2, 0, 2, 0 | 0\n0, 1, -3, 0, -2, 0 | 0\n0, 0, 0, 1, -1, 0 | 0\n0, 0, 0, 0, 0, 1 | 0\n0, 0, 0, 0, 0, 0 | 1 ]\n\nTake it however you want.

There are quite a few, 22 is the smallest such that there are exactly 3 ways. The ones less than one hundred are:\n\n22= 19+3 = 17+5 = 11+11\n24= 19+5 = 17+7 = 13+11\n26= 23+3 = 19+7 = 13+13\n30= 23+7 = 19+11 = 17+13\n40= 37+3 = 29+11 = 23+17\n44= 41+3 = 37+7 = 31+13\n52= 47+5 = 41+11 = 29+23\n56= 53+3 = 43+13 = 37+19\n62= 59+3 = 43+19 = 31+31\n98= 79+19 = 67+31 = 61+37\n\nOf course the more interesting question is Goldbach's Conjecture: Can every even number greater than 2 be expressed as the sum of 2 primes in at least one way? An interesting open problem.

permutation?\n\ni'm not sure what you mean by "see how many it is."

In fraction if the denominators are the same, just add the numerators and copy the denominators, then reduce to lowest term as needed.\n\nExample: 1/2 + 3/2 = 4/2 or 2\nThe numerators are 1 and 3,  adding them will give 4. Then just copy the denominator which is 2. That makes it 4/2, which you need to reduce to lowest term. So 4 divided by 2  (to reduce to the lowest term) so the answer is  2.\n\nIf the denominators are different, then find a common denominator (the least number that can be divided by both denominators) then divide it with the denominator and multiply with the numerator. Then when your numbers are already expressed on fraction with the least common denominator, proceed to adding the numerators and copy the denominator.  \n\nExample:\n\n1/2 + 2/3   (the common denominator will be 6)\n>>1/2 becomes >> 6 divided by 2 = 3  X 1 = 3 -->> 3/6\n>>2/3 becomes >> 6 divided by 3 = 2  X 2 = 4 -->> 4/6\n\nProceed to addition:\n3/6 + 4/6 = 7/6 (divide 7 by 6 to get the lowest term) = 1 and 1/6 is the answer.\n\nGood luck!♥

Find the least number that each can be divided by....Such as(example) 1/2+ 1/3= the lowest denominator would be 6 since 2x3=6 and 3x2=6 so both can be multiplied to make that number. So if you use that common denominator of 6 the problem would be set up like this 3/6+2/6=5/6

are you retarded the least common denominator is 40 der der
