Therefore, GCD of numbers 63, 868, 215, 452 is 1

Given Input Data is 63, 868, 215, 452

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

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 868 is 2 x 2 x 7 x 31

Prime Factorization of 215 is 5 x 43

Prime Factorization of 452 is 2 x 2 x 113

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(63, 868) = 7812

GCD(63, 868) = ( 63 x 868 ) / 7812

GCD(63, 868) = 54684 / 7812

GCD(63, 868) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 215

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

LCM(7, 215) = 1505

GCD(7, 215) = ( 7 x 215 ) / 1505

GCD(7, 215) = 1505 / 1505

GCD(7, 215) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 452

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

LCM(1, 452) = 452

GCD(1, 452) = ( 1 x 452 ) / 452

GCD(1, 452) = 452 / 452

GCD(1, 452) = 1

GCD of 63, 868, 215, 452 is 1
