Given Input Data is 287, 525, 974, 981

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

Prime Factorization of 287 is 7 x 41

Prime Factorization of 525 is 3 x 5 x 5 x 7

Prime Factorization of 974 is 2 x 487

Prime Factorization of 981 is 3 x 3 x 109

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(287, 525) = 21525

GCD(287, 525) = ( 287 x 525 ) / 21525

GCD(287, 525) = 150675 / 21525

GCD(287, 525) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 974

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

LCM(7, 974) = 6818

GCD(7, 974) = ( 7 x 974 ) / 6818

GCD(7, 974) = 6818 / 6818

GCD(7, 974) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 981

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

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

GCD(1, 981) = 981 / 981

GCD(1, 981) = 1

GCD of 287, 525, 974, 981 is 1
