### GCF the 16 and 20 by prime Factorization Prime administrate of 16 and also 20 is (2 × 2 × 2 × 2) and (2 × 2 × 5) respectively. Together visible, 16 and 20 have typical prime factors. Hence, the GCF of 16 and 20 is 2 × 2 = 4.

### GCF of 16 and also 20 through Listing usual Factors Factors of 16: 1, 2, 4, 8, 16Factors of 20: 1, 2, 4, 5, 10, 20

There room 3 typical factors of 16 and 20, that room 1, 2, and 4. Therefore, the greatest usual factor of 16 and 20 is 4.

### GCF the 16 and also 20 by lengthy Division GCF of 16 and 20 is the divisor the we acquire when the remainder i do not care 0 after doing long department repeatedly.

Step 2: due to the fact that the remainder ≠ 0, we will divide the divisor of action 1 (16) through the remainder (4).Step 3: Repeat this process until the remainder = 0.

The equivalent divisor (4) is the GCF the 16 and 20.

## GCF of 16 and also 20 Examples

Example 1: find the best number the divides 16 and also 20 exactly.

Solution:

The biggest number that divides 16 and 20 exactly is their greatest usual factor, i.e. GCF of 16 and also 20.⇒ determinants of 16 and also 20:

Factors that 16 = 1, 2, 4, 8, 16Factors of 20 = 1, 2, 4, 5, 10, 20

Therefore, the GCF the 16 and also 20 is 4.

Example 2: The product of two numbers is 320. If their GCF is 4, what is their LCM?

Solution:

Given: GCF = 4 and also product of numbers = 320∵ LCM × GCF = product of numbers⇒ LCM = Product/GCF = 320/4Therefore, the LCM is 80.

Example 3: discover the GCF the 16 and also 20, if your LCM is 80.

Solution:

∵ LCM × GCF = 16 × 20⇒ GCF(16, 20) = (16 × 20)/80 = 4Therefore, the greatest usual factor the 16 and 20 is 4.
