Given Input Data is 637, 609, 753, 440

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

Prime Factorization of 637 is 7 x 7 x 13

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 753 is 3 x 251

Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11

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(637, 609) = 55419

GCD(637, 609) = ( 637 x 609 ) / 55419

GCD(637, 609) = 387933 / 55419

GCD(637, 609) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 753

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

LCM(7, 753) = 5271

GCD(7, 753) = ( 7 x 753 ) / 5271

GCD(7, 753) = 5271 / 5271

GCD(7, 753) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 440

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

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

GCD(1, 440) = 440 / 440

GCD(1, 440) = 1

GCD of 637, 609, 753, 440 is 1
