Therefore, GCD of numbers 15, 835, 659, 195 is 1

Given Input Data is 15, 835, 659, 195

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 835 is 5 x 167

Prime Factorization of 659 is 659

Prime Factorization of 195 is 3 x 5 x 13

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(15, 835) = 2505

GCD(15, 835) = ( 15 x 835 ) / 2505

GCD(15, 835) = 12525 / 2505

GCD(15, 835) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 659

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

LCM(5, 659) = 3295

GCD(5, 659) = ( 5 x 659 ) / 3295

GCD(5, 659) = 3295 / 3295

GCD(5, 659) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 195

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

LCM(1, 195) = 195

GCD(1, 195) = ( 1 x 195 ) / 195

GCD(1, 195) = 195 / 195

GCD(1, 195) = 1

GCD of 15, 835, 659, 195 is 1
