Greatest Common Divisior

We found the divisors of 86, 54, 61 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 86, 54, 61 is 1.

Therefore, GCD of numbers 86, 54, 61 is 1

Given Input Data is 86, 54, 61

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

Prime Factorization of 86 is 2 x 43

Prime Factorization of 54 is 2 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(86, 54) = 2322

GCD(86, 54) = ( 86 x 54 ) / 2322

GCD(86, 54) = 4644 / 2322

GCD(86, 54) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 61

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

LCM(2, 61) = 122

GCD(2, 61) = ( 2 x 61 ) / 122

GCD(2, 61) = 122 / 122

GCD(2, 61) = 1

GCD of 86, 54, 61 is 1
