Given Input Data is 640, 210, 718

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 718 is 2 x 359

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(640, 210) = 13440

GCD(640, 210) = ( 640 x 210 ) / 13440

GCD(640, 210) = 134400 / 13440

GCD(640, 210) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 718

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(10, 718) = 3590

GCD(10, 718) = ( 10 x 718 ) / 3590

GCD(10, 718) = 7180 / 3590

GCD(10, 718) = 2

GCD of 640, 210, 718 is 2
