Therefore, GCD of numbers 920, 615, 392, 931 is 1

Given Input Data is 920, 615, 392, 931

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

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 931 is 7 x 7 x 19

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(920, 615) = 113160

GCD(920, 615) = ( 920 x 615 ) / 113160

GCD(920, 615) = 565800 / 113160

GCD(920, 615) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 392

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

LCM(5, 392) = 1960

GCD(5, 392) = ( 5 x 392 ) / 1960

GCD(5, 392) = 1960 / 1960

GCD(5, 392) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 931

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

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

GCD(1, 931) = 931 / 931

GCD(1, 931) = 1

GCD of 920, 615, 392, 931 is 1
