Greatest Common Divisior

We found the divisors of 51, 87, 59, 17 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 51, 87, 59, 17 is 1.

Therefore, GCD of numbers 51, 87, 59, 17 is 1

Given Input Data is 51, 87, 59, 17

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

Prime Factorization of 51 is 3 x 17

Prime Factorization of 87 is 3 x 29

Prime Factorization of 59 is 59

Prime Factorization of 17 is 17

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(51, 87) = 1479

GCD(51, 87) = ( 51 x 87 ) / 1479

GCD(51, 87) = 4437 / 1479

GCD(51, 87) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 59

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

LCM(3, 59) = 177

GCD(3, 59) = ( 3 x 59 ) / 177

GCD(3, 59) = 177 / 177

GCD(3, 59) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 17

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

LCM(1, 17) = 17

GCD(1, 17) = ( 1 x 17 ) / 17

GCD(1, 17) = 17 / 17

GCD(1, 17) = 1

GCD of 51, 87, 59, 17 is 1
