Given Input Data is 640, 836, 684

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 836 is 2 x 2 x 11 x 19

Prime Factorization of 684 is 2 x 2 x 3 x 3 x 19

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(640, 836) = 133760

GCD(640, 836) = ( 640 x 836 ) / 133760

GCD(640, 836) = 535040 / 133760

GCD(640, 836) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 684

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

LCM(4, 684) = 684

GCD(4, 684) = ( 4 x 684 ) / 684

GCD(4, 684) = 2736 / 684

GCD(4, 684) = 4

GCD of 640, 836, 684 is 4
