You have to find the largest number that will divide evenly into 84, 90, and 120. This is called the greatest common factor.

First, write out the prime factorization of each of the numbers:

84: red%282%29%2A2%2Ared%283%29%2A7
90: red%282%29%2Ared%283%29%2A3%2A5
120: red%282%29%2A2%2A2%2Ared%283%29%2A5
