    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
