2. Write all numbers as the product of its prime factors
| Prime factors of 64 | = | 26 |
| Prime factors of 96 | = | 25 . 3 |
| Prime factors of 224 | = | 25 . 7 |
3. Choose the common prime factors with the lowest exponent
Common prime factors: 2
Common prime factors with the lowest exponent: 25
4. Calculate the Greatest Common Factor or GCF
Remember, to find the GCF of several numbers you must multiply the common prime factors with the lowest exponent.
GCF = 25 = 32
