Given Input Data is 212, 640, 440

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

Prime Factorization of 212 is 2 x 2 x 53

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

Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11

Highest common occurrences in the given inputs are 2²

Multiplying them we get the GCD as 4

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(212, 640) = 33920

GCD(212, 640) = ( 212 x 640 ) / 33920

GCD(212, 640) = 135680 / 33920

GCD(212, 640) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 440

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

LCM(4, 440) = 440

GCD(4, 440) = ( 4 x 440 ) / 440

GCD(4, 440) = 1760 / 440

GCD(4, 440) = 4

GCD of 212, 640, 440 is 4
