Greatest Common Divisior

We found the divisors of 92, 78, 81, 56 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 92, 78, 81, 56 is 1.

Therefore, GCD of numbers 92, 78, 81, 56 is 1

Given Input Data is 92, 78, 81, 56

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

Prime Factorization of 92 is 2 x 2 x 23

Prime Factorization of 78 is 2 x 3 x 13

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

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(92, 78) = 3588

GCD(92, 78) = ( 92 x 78 ) / 3588

GCD(92, 78) = 7176 / 3588

GCD(92, 78) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 81

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

LCM(2, 81) = 162

GCD(2, 81) = ( 2 x 81 ) / 162

GCD(2, 81) = 162 / 162

GCD(2, 81) = 1

Step3:

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 92, 78, 81, 56 is 1
