### GCF of 8 and 14 by Prime Factorization Prime factorization of 8 and 14 is (2 × 2 × 2) and (2 × 7) respectively. As visible, 8 and 14 have only one common prime factor i.e. 2. Hence, the GCF of 8 and 14 is 2.

### GCF of 8 and 14 by Listing Common Factors Factors of 8: 1, 2, 4, 8Factors of 14: 1, 2, 7, 14

There are 2 common factors of 8 and 14, that are 1 and 2. Therefore, the greatest common factor of 8 and 14 is 2.

### GCF of 8 and 14 by Euclidean Algorithm

As per the Euclidean Algorithm, GCF(X, Y) = GCF(Y, X mod Y)where X > Y and mod is the modulo operator.

Here X = 14 and Y = 8

GCF(14, 8) = GCF(8, 14 mod 8) = GCF(8, 6)GCF(8, 6) = GCF(6, 8 mod 6) = GCF(6, 2)GCF(6, 2) = GCF(2, 6 mod 2) = GCF(2, 0)GCF(2, 0) = 2 (∵ GCF(X, 0) = |X|, where X ≠ 0)

Therefore, the value of GCF of 8 and 14 is 2.

## GCF of 8 and 14 Examples

Example 1: Find the GCF of 8 and 14, if their LCM is 56.

Solution:

∵ LCM × GCF = 8 × 14⇒ GCF(8, 14) = (8 × 14)/56 = 2Therefore, the greatest common factor of 8 and 14 is 2.

Example 2: The product of two numbers is 112. If their GCF is 2, what is their LCM?

Solution:

Given: GCF = 2 and product of numbers = 112∵ LCM × GCF = product of numbers⇒ LCM = Product/GCF = 112/2Therefore, the LCM is 56.

Example 3: For two numbers, GCF = 2 and LCM = 56. If one number is 14, find the other number.

Solution:

Given: GCF (z, 14) = 2 and LCM (z, 14) = 56∵ GCF × LCM = 14 × (z)⇒ z = (GCF × LCM)/14⇒ z = (2 × 56)/14⇒ z = 8Therefore, the other number is 8.
