So the Greatest Common Divisior 97, 18, 55 is 1.

Therefore, GCD of numbers 97, 18, 55 is 1

Given Input Data is 97, 18, 55

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

Prime Factorization of 97 is 97

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 55 is 5 x 11

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(97, 18) = 1746

GCD(97, 18) = ( 97 x 18 ) / 1746

GCD(97, 18) = 1746 / 1746

GCD(97, 18) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 55

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

LCM(1, 55) = 55

GCD(1, 55) = ( 1 x 55 ) / 55

GCD(1, 55) = 55 / 55

GCD(1, 55) = 1

GCD of 97, 18, 55 is 1
