Greatest Common Divisior

We found the divisors of 10, 391, 114, 615 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 10, 391, 114, 615 is 1.

Therefore, GCD of numbers 10, 391, 114, 615 is 1

Given Input Data is 10, 391, 114, 615

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

Prime Factorization of 10 is 2 x 5

Prime Factorization of 391 is 17 x 23

Prime Factorization of 114 is 2 x 3 x 19

Prime Factorization of 615 is 3 x 5 x 41

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(10, 391) = 3910

GCD(10, 391) = ( 10 x 391 ) / 3910

GCD(10, 391) = 3910 / 3910

GCD(10, 391) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 114

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

LCM(1, 114) = 114

GCD(1, 114) = ( 1 x 114 ) / 114

GCD(1, 114) = 114 / 114

GCD(1, 114) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 615

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

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

GCD(1, 615) = 615 / 615

GCD(1, 615) = 1

GCD of 10, 391, 114, 615 is 1
