Therefore, GCD of numbers 640, 485, 52, 637 is 1

Given Input Data is 640, 485, 52, 637

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

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 485 is 5 x 97

Prime Factorization of 52 is 2 x 2 x 13

Prime Factorization of 637 is 7 x 7 x 13

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(640, 485) = 62080

GCD(640, 485) = ( 640 x 485 ) / 62080

GCD(640, 485) = 310400 / 62080

GCD(640, 485) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 52

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

LCM(5, 52) = 260

GCD(5, 52) = ( 5 x 52 ) / 260

GCD(5, 52) = 260 / 260

GCD(5, 52) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 637

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

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

GCD(1, 637) = 637 / 637

GCD(1, 637) = 1

GCD of 640, 485, 52, 637 is 1
