So the Greatest Common Divisior 84, 39, 61 is 1.

Therefore, GCD of numbers 84, 39, 61 is 1

Given Input Data is 84, 39, 61

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

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 39 is 3 x 13

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(84, 39) = 1092

GCD(84, 39) = ( 84 x 39 ) / 1092

GCD(84, 39) = 3276 / 1092

GCD(84, 39) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 61

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

LCM(3, 61) = 183

GCD(3, 61) = ( 3 x 61 ) / 183

GCD(3, 61) = 183 / 183

GCD(3, 61) = 1

GCD of 84, 39, 61 is 1
