Calculator Formula:

The formula to calculate GCF involves identifying the common factors of the given numbers and selecting the largest one

Illustrated Examples:

Example 1

Finding the GCF of 12 and 18:

Common factors of 12: 1, 2, 3, 4, 6, 12

Common factors of 18: 1, 2, 3, 6, 9, 18

Common factors of 18: 1, 2, 3, 6, 9, 18

Therefore, GCF(12, 18) = 6

Example 2

Determining the GCF of 24 and 36:

Common factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

Common factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36

Hence, GCF(24, 36) = 12

Example 3

Calculating the GCF of 35 and 45:

Common factors of 35: 1, 5, 7, 35

Common factors of 45: 1, 3, 5, 9, 15, 45

Thus, GCF(35, 45) = 5

Frequently Asked Questions

GCF is calculated based on the absolute values of the numbers, so the negativity doesn't affect the result.

No, GCF cannot exceed the smallest number as it must be a common factor of both numbers being considered.

Yes, GCF is primarily used for integers, but similar concepts like the greatest common divisor (GCD) extend to other mathematical domains.
