Therefore, GCD of numbers 355, 625, 68, 115 is 1

Given Input Data is 355, 625, 68, 115

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

Prime Factorization of 355 is 5 x 71

Prime Factorization of 625 is 5 x 5 x 5 x 5

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 115 is 5 x 23

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(355, 625) = 44375

GCD(355, 625) = ( 355 x 625 ) / 44375

GCD(355, 625) = 221875 / 44375

GCD(355, 625) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 68

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

LCM(5, 68) = 340

GCD(5, 68) = ( 5 x 68 ) / 340

GCD(5, 68) = 340 / 340

GCD(5, 68) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 115

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

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

GCD(1, 115) = 115 / 115

GCD(1, 115) = 1

GCD of 355, 625, 68, 115 is 1
