Therefore, GCD of numbers 640, 876, 68, 633 is 1

Given Input Data is 640, 876, 68, 633

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

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 876 is 2 x 2 x 3 x 73

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 633 is 3 x 211

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(640, 876) = 140160

GCD(640, 876) = ( 640 x 876 ) / 140160

GCD(640, 876) = 560640 / 140160

GCD(640, 876) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 68

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

LCM(4, 68) = 68

GCD(4, 68) = ( 4 x 68 ) / 68

GCD(4, 68) = 272 / 68

GCD(4, 68) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 633

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

LCM(4, 633) = 2532

GCD(4, 633) = ( 4 x 633 ) / 2532

GCD(4, 633) = 2532 / 2532

GCD(4, 633) = 1

GCD of 640, 876, 68, 633 is 1
