We found the divisors of 122, 417, 130, 787 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 122, 417, 130, 787 is 1.

Therefore, GCD of numbers 122, 417, 130, 787 is 1

Given Input Data is 122, 417, 130, 787

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

Prime Factorization of 122 is 2 x 61

Prime Factorization of 417 is 3 x 139

Prime Factorization of 130 is 2 x 5 x 13

Prime Factorization of 787 is 787

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(122, 417) = 50874

GCD(122, 417) = ( 122 x 417 ) / 50874

GCD(122, 417) = 50874 / 50874

GCD(122, 417) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 130

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

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

GCD(1, 130) = 130 / 130

GCD(1, 130) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 787

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

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

GCD(1, 787) = 787 / 787

GCD(1, 787) = 1

GCD of 122, 417, 130, 787 is 1
