What is the GFC of 315 105 21?
The greatest common factor (GCF, not GFC) of 315, 105 and 21 can be calculated by writing down each number's factors. The factorization for the given numbers is: 315 = 3 x 3 x 5 x 7 105 = 3 x 5 x 7 21 = 3 x 7 The common factors are 3 x 7 = 21, so the GCF of 315, 105 and 21 is 21.
How do you use prime factorization to find the greatest common factor?
1) Get the prime factors for each number. 2) In the result, include all the prime factors that appear in ALL the numbers. If a prime factor appears in different powers, use the lowest power. Example 1: 14 = 2 x 7 21 = 3 x 7 The only common factor is 7. Example 2: 12 = 22 x 3 80 = 24 x 5 Use 22 as the common factor.
What is the hCF of 231 and 315?
