    keep pulling out 2's until you cant (have a odd number) 60 = 2 * 30 = 2 * 2 * 15

    60 = 2 * 30 = 2 * 2 * 15 = 2 * 2 * 3 * 5

    2, 3, and 5 are all prime... 60 = 2^2 * 3 * 5

    Or, Since they give you multiple choice, you can see if only 1 totals 60 A) 2^2 * 11 = 44 B) 2 * 3^2 * 5 = 90 C) 2^3 * 11 = 88 D) 60
