Find the prime factorization of 105
105 = 3 × 5 × 7
Find the prime factorization of 570
570 = 2 × 3 × 5 × 19
To find the gcf, multiply all the prime factors common to both numbers:
Therefore, GCF = 3 × 5
GCF = 15
The greatest common factor (gcf) is also known as greatest common divisor (gcd) or highest common factor (hcf).
