GCF of 12 and 44 Examples

Example 1: The product of two numbers is 528. If their GCF is 4, what is their LCM?

Solution:

Given: GCF = 4 and product of numbers = 528
∵ LCM × GCF = product of numbers
⇒ LCM = Product/GCF = 528/4
Therefore, the LCM is 132.
Example 2: Find the greatest number that divides 12 and 44 exactly.

Solution:

The greatest number that divides 12 and 44 exactly is their greatest common factor, i.e. GCF of 12 and 44.
⇒ Factors of 12 and 44:
- Factors of 12 = 1, 2, 3, 4, 6, 12
- Factors of 44 = 1, 2, 4, 11, 22, 44
Therefore, the GCF of 12 and 44 is 4.
Example 3: For two numbers, GCF = 4 and LCM = 132. If one number is 12, find the other number.

Solution:

Given: GCF (z, 12) = 4 and LCM (z, 12) = 132
∵ GCF × LCM = 12 × (z)
⇒ z = (GCF × LCM)/12
⇒ z = (4 × 132)/12
⇒ z = 44
Therefore, the other number is 44.
