Therefore, GCD of numbers 247, 521, 897, 963 is 1

Given Input Data is 247, 521, 897, 963

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

Prime Factorization of 247 is 13 x 19

Prime Factorization of 521 is 521

Prime Factorization of 897 is 3 x 13 x 23

Prime Factorization of 963 is 3 x 3 x 107

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(247, 521) = 128687

GCD(247, 521) = ( 247 x 521 ) / 128687

GCD(247, 521) = 128687 / 128687

GCD(247, 521) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 897

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

LCM(1, 897) = 897

GCD(1, 897) = ( 1 x 897 ) / 897

GCD(1, 897) = 897 / 897

GCD(1, 897) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 963

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

LCM(1, 963) = 963

GCD(1, 963) = ( 1 x 963 ) / 963

GCD(1, 963) = 963 / 963

GCD(1, 963) = 1

GCD of 247, 521, 897, 963 is 1
