So the Greatest Common Divisior 251, 324, 61 is 1.

Therefore, GCD of numbers 251, 324, 61 is 1

Given Input Data is 251, 324, 61

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

Prime Factorization of 251 is 251

Prime Factorization of 324 is 2 x 2 x 3 x 3 x 3 x 3

Prime Factorization of 61 is 61

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(251, 324) = 81324

GCD(251, 324) = ( 251 x 324 ) / 81324

GCD(251, 324) = 81324 / 81324

GCD(251, 324) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1

GCD of 251, 324, 61 is 1
