We found the divisors of 58, 99, 20 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 58, 99, 20 is 1.

Therefore, GCD of numbers 58, 99, 20 is 1

Given Input Data is 58, 99, 20

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

Prime Factorization of 58 is 2 x 29

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 20 is 2 x 2 x 5

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(58, 99) = 5742

GCD(58, 99) = ( 58 x 99 ) / 5742

GCD(58, 99) = 5742 / 5742

GCD(58, 99) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 1

GCD of 58, 99, 20 is 1
