Given Input Data is 252, 438, 757, 751

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

Prime Factorization of 252 is 2 x 2 x 3 x 3 x 7

Prime Factorization of 438 is 2 x 3 x 73

Prime Factorization of 757 is 757

Prime Factorization of 751 is 751

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(252, 438) = 18396

GCD(252, 438) = ( 252 x 438 ) / 18396

GCD(252, 438) = 110376 / 18396

GCD(252, 438) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 757

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

LCM(6, 757) = 4542

GCD(6, 757) = ( 6 x 757 ) / 4542

GCD(6, 757) = 4542 / 4542

GCD(6, 757) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 751

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

LCM(1, 751) = 751

GCD(1, 751) = ( 1 x 751 ) / 751

GCD(1, 751) = 751 / 751

GCD(1, 751) = 1

GCD of 252, 438, 757, 751 is 1
