Given Input Data is 297, 477, 15, 860

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

Prime Factorization of 297 is 3 x 3 x 3 x 11

Prime Factorization of 477 is 3 x 3 x 53

Prime Factorization of 15 is 3 x 5

Prime Factorization of 860 is 2 x 2 x 5 x 43

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(297, 477) = 15741

GCD(297, 477) = ( 297 x 477 ) / 15741

GCD(297, 477) = 141669 / 15741

GCD(297, 477) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 15

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

LCM(9, 15) = 45

GCD(9, 15) = ( 9 x 15 ) / 45

GCD(9, 15) = 135 / 45

GCD(9, 15) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 860

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

LCM(3, 860) = 2580

GCD(3, 860) = ( 3 x 860 ) / 2580

GCD(3, 860) = 2580 / 2580

GCD(3, 860) = 1

GCD of 297, 477, 15, 860 is 1
