Greatest Common Divisior

We found the divisors of 84, 83, 28 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 84, 83, 28 is 1.

Therefore, GCD of numbers 84, 83, 28 is 1

Given Input Data is 84, 83, 28

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

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 83 is 83

Prime Factorization of 28 is 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(84, 83) = 6972

GCD(84, 83) = ( 84 x 83 ) / 6972

GCD(84, 83) = 6972 / 6972

GCD(84, 83) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 28

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

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

GCD(1, 28) = 28 / 28

GCD(1, 28) = 1

GCD of 84, 83, 28 is 1
