What is the GCF of 18, 24, and 36?

The Greatest Common Factor (GCF) of 18, 24, and 36 is 6.

To find the GCF of these numbers, we can use the prime factorization method:

1. First, find the prime factors of each number:
   • 18 = 2 × 3 × 3
   • 24 = 2 × 2 × 2 × 3
   • 36 = 2 × 2 × 3 × 3
2. Next, identify the common prime factors:
   • The common prime factors are 2 and 3.
3. Multiply the lowest powers of the common prime factors:
   • 2 × 3 = 6

Therefore, the GCF of 18, 24, and 36 is 6.
