Therefore, GCD of numbers 54, 99, 28 is 1

Given Input Data is 54, 99, 28

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

Prime Factorization of 54 is 2 x 3 x 3 x 3

Prime Factorization of 99 is 3 x 3 x 11

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(54, 99) = 594

GCD(54, 99) = ( 54 x 99 ) / 594

GCD(54, 99) = 5346 / 594

GCD(54, 99) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 28

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

LCM(9, 28) = 252

GCD(9, 28) = ( 9 x 28 ) / 252

GCD(9, 28) = 252 / 252

GCD(9, 28) = 1

GCD of 54, 99, 28 is 1
