Therefore, GCD of numbers 327, 820, 85 is 1

Given Input Data is 327, 820, 85

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

Prime Factorization of 327 is 3 x 109

Prime Factorization of 820 is 2 x 2 x 5 x 41

Prime Factorization of 85 is 5 x 17

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(327, 820) = 268140

GCD(327, 820) = ( 327 x 820 ) / 268140

GCD(327, 820) = 268140 / 268140

GCD(327, 820) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 85

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

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

GCD(1, 85) = 85 / 85

GCD(1, 85) = 1

GCD of 327, 820, 85 is 1
