Therefore, GCD of numbers 15, 219, 931, 937 is 1

Given Input Data is 15, 219, 931, 937

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 219 is 3 x 73

Prime Factorization of 931 is 7 x 7 x 19

Prime Factorization of 937 is 937

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(15, 219) = 1095

GCD(15, 219) = ( 15 x 219 ) / 1095

GCD(15, 219) = 3285 / 1095

GCD(15, 219) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 931

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

LCM(3, 931) = 2793

GCD(3, 931) = ( 3 x 931 ) / 2793

GCD(3, 931) = 2793 / 2793

GCD(3, 931) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 937

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

LCM(1, 937) = 937

GCD(1, 937) = ( 1 x 937 ) / 937

GCD(1, 937) = 937 / 937

GCD(1, 937) = 1

GCD of 15, 219, 931, 937 is 1
