Therefore, GCD of numbers 391, 442, 92, 129 is 1

Given Input Data is 391, 442, 92, 129

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

Prime Factorization of 391 is 17 x 23

Prime Factorization of 442 is 2 x 13 x 17

Prime Factorization of 92 is 2 x 2 x 23

Prime Factorization of 129 is 3 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(391, 442) = 10166

GCD(391, 442) = ( 391 x 442 ) / 10166

GCD(391, 442) = 172822 / 10166

GCD(391, 442) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 92

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

LCM(17, 92) = 1564

GCD(17, 92) = ( 17 x 92 ) / 1564

GCD(17, 92) = 1564 / 1564

GCD(17, 92) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 129

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

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

GCD(1, 129) = 129 / 129

GCD(1, 129) = 1

GCD of 391, 442, 92, 129 is 1
