Answer: GCF the 8 and 16 is 8. Explanation:

The GCF of two non-zero integers, x(8) and y(16), is the biggest positive essence m(8) the divides both x(8) and also y(16) without any remainder.

Let's look at the different methods for finding the GCF the 8 and also 16.

Prime administrate MethodUsing Euclid's AlgorithmLong division Method

### GCF that 8 and also 16 by prime Factorization Prime factorization of 8 and also 16 is (2 × 2 × 2) and (2 × 2 × 2 × 2) respectively. As visible, 8 and also 16 have usual prime factors. Hence, the GCF that 8 and also 16 is 2 × 2 × 2 = 8.

### GCF the 8 and also 16 by Euclidean Algorithm

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

Here X = 16 and Y = 8

GCF(16, 8) = GCF(8, 16 mod 8) = GCF(8, 0)GCF(8, 0) = 8 (∵ GCF(X, 0) = |X|, whereby X ≠ 0)

Therefore, the value of GCF of 8 and 16 is 8.

### GCF that 8 and 16 by lengthy Division GCF of 8 and 16 is the divisor that we obtain when the remainder becomes 0 ~ doing long department repeatedly.

Step 2: because the remainder = 0, the divisor (8) is the GCF the 8 and also 16.

The corresponding divisor (8) is the GCF of 8 and also 16.
