Therefore, GCD of numbers 664, 648, 875, 187 is 1

Given Input Data is 664, 648, 875, 187

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

Prime Factorization of 664 is 2 x 2 x 2 x 83

Prime Factorization of 648 is 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime Factorization of 875 is 5 x 5 x 5 x 7

Prime Factorization of 187 is 11 x 17

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(664, 648) = 53784

GCD(664, 648) = ( 664 x 648 ) / 53784

GCD(664, 648) = 430272 / 53784

GCD(664, 648) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 875

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

LCM(8, 875) = 7000

GCD(8, 875) = ( 8 x 875 ) / 7000

GCD(8, 875) = 7000 / 7000

GCD(8, 875) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 187

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

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

GCD(1, 187) = 187 / 187

GCD(1, 187) = 1

GCD of 664, 648, 875, 187 is 1
