We found the divisors of 26, 20, 87 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 26, 20, 87 is 1.

Therefore, GCD of numbers 26, 20, 87 is 1

Given Input Data is 26, 20, 87

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

Prime Factorization of 26 is 2 x 13

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 87 is 3 x 29

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(26, 20) = 260

GCD(26, 20) = ( 26 x 20 ) / 260

GCD(26, 20) = 520 / 260

GCD(26, 20) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 87

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

LCM(2, 87) = 174

GCD(2, 87) = ( 2 x 87 ) / 174

GCD(2, 87) = 174 / 174

GCD(2, 87) = 1

GCD of 26, 20, 87 is 1
