GCF of 64 and 144 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 = 144 and Y = 64

• GCF(144, 64) = GCF(64, 144 mod 64) = GCF(64, 16)
• GCF(64, 16) = GCF(16, 64 mod 16) = GCF(16, 0)
• GCF(16, 0) = 16 (∵ GCF(X, 0) = |X|, where X ≠ 0)

Therefore, the value of GCF of 64 and 144 is 16.

GCF of 64 and 144 by Long Division

GCF of 64 and 144 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.

• Step 1: Divide 144 (larger number) by 64 (smaller number).
• Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (64) by the remainder (16).
• Step 3: Repeat this process until the remainder = 0.

The corresponding divisor (16) is the GCF of 64 and 144.
