SOLUTION: the greatest common factors 310,120,252 using the prime factoring method

Question 274041: the greatest common factors 310,120,252 using the prime factoring method
Answer by jsmallt9(3758) (Show Source): You can put this solution on YOUR website!
310 = 31 * 10 = 31 * 5 * 2
120 = 12 * 10 = 3 * 4 * 2 * 5 = 3 * 2 * 2 * 2 * 5
252 = 4 * 63 = 2 * 2 * 7 * 9 = 2 * 2 * 7 * 3 * 3
I'm going ro rearrange the factors and use spacing to make the GCF more obvious:

310 = 2                 * 5     * 31
120 = 2 * 2 * 2 * 3     * 5
252 = 2 * 2     * 3 * 3     * 7

From this view it should be clear that there is only one factor common to all three numbers: 2. The GCF is 2.
