So the Greatest Common Divisior 73, 89, 28 is 1.

Therefore, GCD of numbers 73, 89, 28 is 1

Given Input Data is 73, 89, 28

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

Prime Factorization of 73 is 73

Prime Factorization of 89 is 89

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(73, 89) = 6497

GCD(73, 89) = ( 73 x 89 ) / 6497

GCD(73, 89) = 6497 / 6497

GCD(73, 89) = 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 73, 89, 28 is 1
