The greatest common factor of 100 and 144 is 4.The factors of 100 are 2*2*5*5.The factors of 144 are 2*2*2*2*3*3.Since there are two sets of 2 in both 100 and 144, 2*2=4 and this is your greatest common factor.
The greatest common factor of 144 and 175 is 1. Factoring completely, we determine: 144 = 12 * 12 = 3 * 3 * 4 * 4 = 3 * 3 * 2 * 2 * 2 * 2 * 1 175 = 7 * 25 = 7 * 5 * 5 * 1 Since the only factor these have in common is 1, 1 is their greatest common factor.
Since 12 is a factor of 144 and 12 is the largest factor of itself, the greatest common factor of 12 and 144 is 12.
The greatest common factor of 144 , 324 = 36
