Factors the 9: 1, 3, 9Factors the 12: 1, 2, 3, 4, 6, 12

There space 2 common factors that 9 and also 12, that space 1 and also 3. Therefore, the greatest common factor that 9 and also 12 is 3.

GCF that 9 and also 12 Examples

Example 1: The product of 2 numbers is 108. If your GCF is 3, what is your LCM?

Solution:

Given: GCF = 3 and also product of numbers = 108∵ LCM × GCF = product the numbers⇒ LCM = Product/GCF = 108/3Therefore, the LCM is 36.

Example 2: discover the GCF of 9 and 12, if their LCM is 36.

Solution:

∵ LCM × GCF = 9 × 12⇒ GCF(9, 12) = (9 × 12)/36 = 3Therefore, the greatest usual factor of 9 and also 12 is 3.

Example 3: find the greatest number the divides 9 and also 12 exactly.

Solution:

The best number the divides 9 and 12 precisely is their greatest common factor, i.e. GCF the 9 and 12.⇒ factors of 9 and also 12:

Factors that 9 = 1, 3, 9Factors of 12 = 1, 2, 3, 4, 6, 12

Therefore, the GCF that 9 and 12 is 3.
