Given Input Data is 520, 956, 208, 127

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

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 956 is 2 x 2 x 239

Prime Factorization of 208 is 2 x 2 x 2 x 2 x 13

Prime Factorization of 127 is 127

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(520, 956) = 124280

GCD(520, 956) = ( 520 x 956 ) / 124280

GCD(520, 956) = 497120 / 124280

GCD(520, 956) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 208

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

LCM(4, 208) = 208

GCD(4, 208) = ( 4 x 208 ) / 208

GCD(4, 208) = 832 / 208

GCD(4, 208) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 127

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

LCM(4, 127) = 508

GCD(4, 127) = ( 4 x 127 ) / 508

GCD(4, 127) = 508 / 508

GCD(4, 127) = 1

GCD of 520, 956, 208, 127 is 1
