Greatest Common Divisior

We found the divisors of 11, 13, 87 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 11, 13, 87 is 1.

Therefore, GCD of numbers 11, 13, 87 is 1

Given Input Data is 11, 13, 87

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

Prime Factorization of 11 is 11

Prime Factorization of 13 is 13

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(11, 13) = 143

GCD(11, 13) = ( 11 x 13 ) / 143

GCD(11, 13) = 143 / 143

GCD(11, 13) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 87

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

LCM(1, 87) = 87

GCD(1, 87) = ( 1 x 87 ) / 87

GCD(1, 87) = 87 / 87

GCD(1, 87) = 1

GCD of 11, 13, 87 is 1
