Greatest Common Divisior

We found the divisors of 55, 81, 32 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 55, 81, 32 is 1.

Therefore, GCD of numbers 55, 81, 32 is 1

Given Input Data is 55, 81, 32

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

Prime Factorization of 55 is 5 x 11

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 32 is 2 x 2 x 2 x 2 x 2

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(55, 81) = 4455

GCD(55, 81) = ( 55 x 81 ) / 4455

GCD(55, 81) = 4455 / 4455

GCD(55, 81) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 32

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

LCM(1, 32) = 32

GCD(1, 32) = ( 1 x 32 ) / 32

GCD(1, 32) = 32 / 32

GCD(1, 32) = 1

GCD of 55, 81, 32 is 1
