what is the least common multiple of 12, 20, and 35?

The LCM is the lowest (or least) number which contains all of the prime factors contained in each of the given numbers, so you need to factor each number out:\n12 = 2 X 2 X 3\n20 = 2 X 2 X 5\n35 = 5 X 7\n\nSo you need 2, 2, 3, 5, and 7\n2 X 2 X 3 X 5 X 7 = 420\n\nIt's 420.  Smoke 'em if you got 'em!

Calculate the least common multiple of the times of the three strands:\n\nRed strand = 4 seconds (= 2 * 2)\nGreen Strand = 6 seconds (= 2 * 3)\nWhite strand = 10 seconds (= 2 * 5)\n\nThe least common multiple is 2 * 2 * 3 * 5 = 60 seconds.  So all strands will blink together at the 60th second.\n\nSecond 4 = Red\nSecond 6 = Green\nSecond 8 = Red\nSecond 10 = White\nSecond 12 = Red and Green\nSecond 16 = Red\nSecond 18 = Green\nSecond 20 = Red\nSecond 24 = Red and Green\nSecond 28 = Red\nSecond 30 = White and Green\nSecond 32 = Red\nSecond 36 = Red and Green\nSecond 40 = Red and White\nSecond 42 = Green\nSecond 44 = Red\nSecond 48 = Red and Green\nSecond 50 = White\nSecond 52 = Red\nSecond 54 = Green\nSecond 56 = Red\nSecond 60 = Red and Green and White

The least common multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.

GCF=greatest common factor is the no that is the gteatest factor of two or more no is the GCF \n\nEX) 12=1,2,3,4,6,12\n    30=1,2,3,5,6,10,15,30\n\nAs you can see 6 is the greatest in here that is common with 12 and 30

There are two common ways.   If the numbers are small and you can eyeball it, the best way is to split each number into it's prime factors and then cancel out.\n\nE.g. 12 and 30\n\n12 = 2 x 2 x 3\n30 = 2 x 3 x 5\n\nGreatest common divisor = 2 x 3 = 6\n\nThe least common multiple is related to the GCD by\n\nA x B = GCD x LCM\n\nThe better way to do GCD's for big numbers is to note that if a number divides A and B, then it divides A - B, A + B, and in fact A - k*B for any k (i.e. A minus any multiple of B).\n\nSo you take the bigger number, say A, do long division with remainder to get:\n\nA = k * B + remainder\n\nGCD(A, B) = GCD( B, remainder)\n\nBoth B and the remainder are smaller than A.  You keep doing that until the number divides exactly or you end up with one.  If the number divides exactly that is the GCD, otherwise it's one.\n\nE.g. \n30 = 12 * 2 + 6\n12 = 6 * 2 exactly GCD = 6

12/2 since 3 goes into 12 and is the least Least common 12 divide by 2.

For five consecutive, there are 34 possibilities because you could start with 1, 2, 3,..., or 34\nYou can't start with 35 because then you would have\n35, 36, 37, 38 which is only four numbers.\nI'm not sure about the other two.\nNote: The answer to the other two are not 35 and 36.

your question has a problem...............\nif the sum is 13, then the other number has to be -35, which will not meet your other condition
