Therefore, GCD of numbers 231, 639, 375, 131 is 1

Given Input Data is 231, 639, 375, 131

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

Prime Factorization of 231 is 3 x 7 x 11

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 375 is 3 x 5 x 5 x 5

Prime Factorization of 131 is 131

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(231, 639) = 49203

GCD(231, 639) = ( 231 x 639 ) / 49203

GCD(231, 639) = 147609 / 49203

GCD(231, 639) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 375

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

LCM(3, 375) = 375

GCD(3, 375) = ( 3 x 375 ) / 375

GCD(3, 375) = 1125 / 375

GCD(3, 375) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 131

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

LCM(3, 131) = 393

GCD(3, 131) = ( 3 x 131 ) / 393

GCD(3, 131) = 393 / 393

GCD(3, 131) = 1

GCD of 231, 639, 375, 131 is 1
