Given Input Data is 287, 637, 25, 977

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

Prime Factorization of 287 is 7 x 41

Prime Factorization of 637 is 7 x 7 x 13

Prime Factorization of 25 is 5 x 5

Prime Factorization of 977 is 977

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(287, 637) = 26117

GCD(287, 637) = ( 287 x 637 ) / 26117

GCD(287, 637) = 182819 / 26117

GCD(287, 637) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 25

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

LCM(7, 25) = 175

GCD(7, 25) = ( 7 x 25 ) / 175

GCD(7, 25) = 175 / 175

GCD(7, 25) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 977

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

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

GCD(1, 977) = 977 / 977

GCD(1, 977) = 1

GCD of 287, 637, 25, 977 is 1
