Therefore, GCD of numbers 261, 207, 167, 634 is 1

Given Input Data is 261, 207, 167, 634

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

Prime Factorization of 261 is 3 x 3 x 29

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 167 is 167

Prime Factorization of 634 is 2 x 317

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(261, 207) = 6003

GCD(261, 207) = ( 261 x 207 ) / 6003

GCD(261, 207) = 54027 / 6003

GCD(261, 207) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 167

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

LCM(9, 167) = 1503

GCD(9, 167) = ( 9 x 167 ) / 1503

GCD(9, 167) = 1503 / 1503

GCD(9, 167) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 634

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

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

GCD(1, 634) = 634 / 634

GCD(1, 634) = 1

GCD of 261, 207, 167, 634 is 1
