What's the GCF of 3?

The GCF of 3 and 12 is 3. To calculate the GCF (Greatest Common Factor) of 3 and 12, we need to factor each number (factors of 3 = 1, 3; factors of 12 = 1, 2, 3, 4, 6, 12) and choose the greatest factor that exactly divides both 3 and 12, i.e., 3.

What's the GCF of 7?

To find the GCF of 7 and 28, we will find the prime factorization of the given numbers, i.e. 7 = 7; 28 = 2 × 2 × 7. ⇒ Since 7 is the only common prime factor of 7 and 28. Hence, GCF (7, 28) = 7.

What is the GCD of 18 and 36?

The GCF of 18 and 36 is 18. To calculate the greatest common factor (GCF) of 18 and 36, we need to factor each number (factors of 18 = 1, 2, 3, 6, 9, 18; factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36) and choose the greatest factor that exactly divides both 18 and 36, i.e., 18.
