Steps to find GCF

1. Find the prime factorization of 4
   4 = 2 × 2
2. Find the prime factorization of 7
   7 = 7
3. To find the gcf, multiply all the prime factors common to both numbers:
   
   Therefore, GCF = 1

The greatest common factor (gcf) is also known as greatest common divisor (gcd) or highest common factor (hcf).
