Given Input Data is 172, 502, 70, 511

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

Prime Factorization of 172 is 2 x 2 x 43

Prime Factorization of 502 is 2 x 251

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 511 is 7 x 73

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(172, 502) = 43172

GCD(172, 502) = ( 172 x 502 ) / 43172

GCD(172, 502) = 86344 / 43172

GCD(172, 502) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 70

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

LCM(2, 70) = 70

GCD(2, 70) = ( 2 x 70 ) / 70

GCD(2, 70) = 140 / 70

GCD(2, 70) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 511

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

LCM(2, 511) = 1022

GCD(2, 511) = ( 2 x 511 ) / 1022

GCD(2, 511) = 1022 / 1022

GCD(2, 511) = 1

GCD of 172, 502, 70, 511 is 1
