Given Input Data is 516, 640, 615, 329

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

Prime Factorization of 516 is 2 x 2 x 3 x 43

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

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 329 is 7 x 47

The above numbers do not have any common prime factor. So GCD is 1

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(516, 640) = 82560

GCD(516, 640) = ( 516 x 640 ) / 82560

GCD(516, 640) = 330240 / 82560

GCD(516, 640) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 615

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

LCM(4, 615) = 2460

GCD(4, 615) = ( 4 x 615 ) / 2460

GCD(4, 615) = 2460 / 2460

GCD(4, 615) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 329

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

LCM(1, 329) = 329

GCD(1, 329) = ( 1 x 329 ) / 329

GCD(1, 329) = 329 / 329

GCD(1, 329) = 1

GCD of 516, 640, 615, 329 is 1
