Methods to Find GCF of 10 and 16
Let's look at the different methods for finding the GCF of 10 and 16.
 Using Euclid's Algorithm
 Long Division Method
 Prime Factorization Method
GCF of 10 and 16 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 = 16 and Y = 10
 GCF(16, 10) = GCF(10, 16 mod 10) = GCF(10, 6)
 GCF(10, 6) = GCF(6, 10 mod 6) = GCF(6, 4)
 GCF(6, 4) = GCF(4, 6 mod 4) = GCF(4, 2)
 GCF(4, 2) = GCF(2, 4 mod 2) = GCF(2, 0)
 GCF(2, 0) = 2 (∵ GCF(X, 0) = X, where X ≠ 0)
Therefore, the value of GCF of 10 and 16 is 2.
GCF of 10 and 16 by Long Division
GCF of 10 and 16 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.
 Step 1: Divide 16 (larger number) by 10 (smaller number).
 Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (10) by the remainder (6).
 Step 3: Repeat this process until the remainder = 0.
The corresponding divisor (2) is the GCF of 10 and 16.
