1. find each multiplication problem that goes into each number starting with 2 and go up. do that with the other number you are comparing and then compare.

example

36 and 12

36 = 1,2,3,4,6,9,12,18,36 are factors 36
1x36
2x18
3x12
4x9
6

12 = 1,2,3,4,6,12 are factors of 12
1x12
2x6
3x4

now you compare both numbers of their factors
12 = 1,2,3,4,6,12
36 = 1,2,3,4,6,9,12,18,36
find the numbers they have in common which are 1,2,3,4,. then look at which number is greater
