Greatest Common Divisior

We found the divisors of 32, 42, 51 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 32, 42, 51 is 1.

Therefore, GCD of numbers 32, 42, 51 is 1

Given Input Data is 32, 42, 51

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 42 is 2 x 3 x 7

Prime Factorization of 51 is 3 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, 42) = 672

GCD(32, 42) = ( 32 x 42 ) / 672

GCD(32, 42) = 1344 / 672

GCD(32, 42) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 51

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

LCM(2, 51) = 102

GCD(2, 51) = ( 2 x 51 ) / 102

GCD(2, 51) = 102 / 102

GCD(2, 51) = 1

GCD of 32, 42, 51 is 1
