Given Input Data is 28, 156, 525, 759

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 156 is 2 x 2 x 3 x 13

Prime Factorization of 525 is 3 x 5 x 5 x 7

Prime Factorization of 759 is 3 x 11 x 23

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(28, 156) = 1092

GCD(28, 156) = ( 28 x 156 ) / 1092

GCD(28, 156) = 4368 / 1092

GCD(28, 156) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 525

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

LCM(4, 525) = 2100

GCD(4, 525) = ( 4 x 525 ) / 2100

GCD(4, 525) = 2100 / 2100

GCD(4, 525) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 759

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

LCM(1, 759) = 759

GCD(1, 759) = ( 1 x 759 ) / 759

GCD(1, 759) = 759 / 759

GCD(1, 759) = 1

GCD of 28, 156, 525, 759 is 1
