Therefore, GCD of numbers 772, 170, 239 is 1

Given Input Data is 772, 170, 239

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

Prime Factorization of 772 is 2 x 2 x 193

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 239 is 239

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(772, 170) = 65620

GCD(772, 170) = ( 772 x 170 ) / 65620

GCD(772, 170) = 131240 / 65620

GCD(772, 170) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 239

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

LCM(2, 239) = 478

GCD(2, 239) = ( 2 x 239 ) / 478

GCD(2, 239) = 478 / 478

GCD(2, 239) = 1

GCD of 772, 170, 239 is 1
