What is the greatest common factor GCF of 72?
Prime factorization
- Prime factors of 72 are: 2, 2, 2, 3, 3 ,
- Prime factors of 40 are: 2, 2, 2, 5 ,
- In other words, we can write: 72 = 2 * 2 * 2 * 3 * 3 and 40 = 2 * 2 * 2 * 5 ,
- The part which is shared in both cases is 2 * 2 * 2 = 8 , and that’s the Greatest Common Factor.
