Greatest Common Divisior

We found the divisors of 87, 18, 86 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 87, 18, 86 is 1.

Therefore, GCD of numbers 87, 18, 86 is 1

Given Input Data is 87, 18, 86

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

Prime Factorization of 87 is 3 x 29

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 86 is 2 x 43

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(87, 18) = 522

GCD(87, 18) = ( 87 x 18 ) / 522

GCD(87, 18) = 1566 / 522

GCD(87, 18) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 86

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

LCM(3, 86) = 258

GCD(3, 86) = ( 3 x 86 ) / 258

GCD(3, 86) = 258 / 258

GCD(3, 86) = 1

GCD of 87, 18, 86 is 1
