Greatest Common Divisior

We found the divisors of 32, 78, 85 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 32, 78, 85 is 1.

Therefore, GCD of numbers 32, 78, 85 is 1

Given Input Data is 32, 78, 85

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 78 is 2 x 3 x 13

Prime Factorization of 85 is 5 x 17

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, 78) = 1248

GCD(32, 78) = ( 32 x 78 ) / 1248

GCD(32, 78) = 2496 / 1248

GCD(32, 78) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 85

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

LCM(2, 85) = 170

GCD(2, 85) = ( 2 x 85 ) / 170

GCD(2, 85) = 170 / 170

GCD(2, 85) = 1

GCD of 32, 78, 85 is 1
