Greatest Common Divisior

We found the divisors of 20, 55, 92 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 20, 55, 92 is 1.

Therefore, GCD of numbers 20, 55, 92 is 1

Given Input Data is 20, 55, 92

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

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 55 is 5 x 11

Prime Factorization of 92 is 2 x 2 x 23

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(20, 55) = 220

GCD(20, 55) = ( 20 x 55 ) / 220

GCD(20, 55) = 1100 / 220

GCD(20, 55) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 92

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

LCM(5, 92) = 460

GCD(5, 92) = ( 5 x 92 ) / 460

GCD(5, 92) = 460 / 460

GCD(5, 92) = 1

GCD of 20, 55, 92 is 1
