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

Prime factors of 221=13 . 17
Prime factors of 250=2 . 53
Prime factors of 286=2 . 11 . 13

3. Choose the common prime factors with the lowest exponent

Common prime factors: None

Common prime factors with the lowest exponent: None

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.

Since there are not common prime factors the GCF is 1
