What is the factor tree of 1200?
813960
To get a factor tree, start with picking a couple factors of 1200 (say 30 and 40).  Draw them as two branches under 1200.  Now continue doing that for each number (30 = 5 x 6, 40 = 4 x 10).  Keep branching until you get to a prime number.  When you read all the "leaves" you'll have your prime factorization.\n\n... 1200\n..../ .... &#92;\n.30 .....40\n./ .&#92; .... /. &#92;\n5  6... 4 10\n.. / &#92; ../ &#92; . / &#92;\n..2 3 2 2 2 5\n\n1,200 = 2 x 2 x 2 x 2 x 3 x 5 x 5\n\nNote: it doesn't matter how you pick your factors, since you'll still get to the same leaves.  The example above is just one way to create a factor tree for 1,200.  You could have started with 12 x 100, for example.  Just pick whatever first comes to mind.

Just try out small numbers. 1, 2, 3, 4, 6, 8 all work. Once you start doing anything higher, the second factor becomes smaller again, so the others are 96/8, 96/6, 96/4, 96/3, 96/2, 96/1.\nIn all: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96.

the first step is basically to factor 120175.  the obvious factor to do first is 5.  this gives us 5*24035.  then factoring another 5 gives us 5*5*4807.  since 4807 obviously isn't divisible by 5 or 2, try 3.  doesn't work - so keep on trying the next biggest prime number (1,2,3,5,7,11,13,17...)  turns out that 4807 is divisible by 11.  this gives us 5*5*11*437.  keep on going and you get 5*5*11*19*23.  just checking, yes - 5*5*11*19*23=120175.\n\nnow converting these factors into letters, you get the available letters EEKSW.  this can be rearranged to be WEEKS.  however, remember that 5*5*11*19*23 can also be written as 25*11*19*23, since this also equals 120175.  this means the word could also have KSWY.  but i don't think you can rearrange those letters to make a word.\n\nso therefore the english word encoded as 120175 is WEEKS.  basically, you factored the number, converted them into letters, and solved the anagram.\n\n[[edit]]\n\ninuyasha's right - there could be an infinite number of "a"s in there too since 5*5*11*19*23 = 5*5*11*19*23*1*1*1*...\n\nhowever, this gives us WEEKS+AAA... so using the online anagram solver, found at http://wordsmith.org/anagram/ , there are no words that have "WEEKS" in them and "A"s.  therefore, the answer is still WEEKS.

factors of 81 are 1,3,9,27,81\nfactors of 87 are 1,3,29,87\n\nif you mean factorize 87= 3*29 and 81 = 3*3*3*3

60.  Because 120 doesn't go into 1260 evenly.  But 60 (or 120/2), which would be your next choice, does.  And if 60 didn't work, you would have next tried 40 (120/3), then 30 (120/4), then 24 (120/5) and so on.

1224=2*2*3*3*17\n4000=2*2*2*2*2*5*5*5\n6336=2*2*2*2*2*2*2*11\n3125=5*5*5*5*5\n\nNone. There is no prime # that is a factor of all; therefore, there is no #, prime/composite, that goes into all of them.

Biblically speaking, 12 is a number representing the beginning of completion (think about the 12 tribes of Isreal as the foundation of the chosen people of God, or the 12 disciples as those chosen to evangelize the entire world).  The number 144 is the square of 12, completion times completion.  Multiplied by 1000 is the number you quote, from the book of Revelation.  It represents God's desire for all peoples of the earth to come to salvation in Jesus, and it tells us he will not rest and the world will not end until the gospel has been preached to the ends of the earth.
