Therefore, GCD of numbers 636, 244, 177, 665 is 1

Given Input Data is 636, 244, 177, 665

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

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 244 is 2 x 2 x 61

Prime Factorization of 177 is 3 x 59

Prime Factorization of 665 is 5 x 7 x 19

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(636, 244) = 38796

GCD(636, 244) = ( 636 x 244 ) / 38796

GCD(636, 244) = 155184 / 38796

GCD(636, 244) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 177

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

LCM(4, 177) = 708

GCD(4, 177) = ( 4 x 177 ) / 708

GCD(4, 177) = 708 / 708

GCD(4, 177) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 665

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

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

GCD(1, 665) = 665 / 665

GCD(1, 665) = 1

GCD of 636, 244, 177, 665 is 1
