Therefore, GCD of numbers 530, 302, 745 is 1

Given Input Data is 530, 302, 745

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

Prime Factorization of 530 is 2 x 5 x 53

Prime Factorization of 302 is 2 x 151

Prime Factorization of 745 is 5 x 149

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(530, 302) = 80030

GCD(530, 302) = ( 530 x 302 ) / 80030

GCD(530, 302) = 160060 / 80030

GCD(530, 302) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 745

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

LCM(2, 745) = 1490

GCD(2, 745) = ( 2 x 745 ) / 1490

GCD(2, 745) = 1490 / 1490

GCD(2, 745) = 1

GCD of 530, 302, 745 is 1
