Therefore, GCD of numbers 663, 431, 72, 881 is 1

Given Input Data is 663, 431, 72, 881

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

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 431 is 431

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 881 is 881

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(663, 431) = 285753

GCD(663, 431) = ( 663 x 431 ) / 285753

GCD(663, 431) = 285753 / 285753

GCD(663, 431) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 72

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

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

GCD(1, 72) = 72 / 72

GCD(1, 72) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 881

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

LCM(1, 881) = 881

GCD(1, 881) = ( 1 x 881 ) / 881

GCD(1, 881) = 881 / 881

GCD(1, 881) = 1

GCD of 663, 431, 72, 881 is 1
