Therefore, GCD of numbers 502, 639, 671 is 1

Given Input Data is 502, 639, 671

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

Prime Factorization of 502 is 2 x 251

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 671 is 11 x 61

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(502, 639) = 320778

GCD(502, 639) = ( 502 x 639 ) / 320778

GCD(502, 639) = 320778 / 320778

GCD(502, 639) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 671

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

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

GCD(1, 671) = 671 / 671

GCD(1, 671) = 1

GCD of 502, 639, 671 is 1
