Answer»

2. Write all numbers as the product of its prime factors

Prime factors of 28 = 22 . 7

Prime factors of 42 = 2 . 3 . 7

Prime factors of 49 = 72

3. Choose the common prime factors with the lowest exponent

Common prime factors: 7

Common prime factors with the lowest exponent: 71

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 = 71 = 7
