Greatest Common Divisior

We found the divisors of 32, 85, 56 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 32, 85, 56 is 1.

Therefore, GCD of numbers 32, 85, 56 is 1

Given Input Data is 32, 85, 56

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

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

Prime Factorization of 85 is 5 x 17

Prime Factorization of 56 is 2 x 2 x 2 x 7

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(32, 85) = 2720

GCD(32, 85) = ( 32 x 85 ) / 2720

GCD(32, 85) = 2720 / 2720

GCD(32, 85) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 56

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

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

GCD(1, 56) = 56 / 56

GCD(1, 56) = 1

GCD of 32, 85, 56 is 1
