Greatest Common Divisior

We found the divisors of 84, 9, 76, 87 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 84, 9, 76, 87 is 1.

Therefore, GCD of numbers 84, 9, 76, 87 is 1

Given Input Data is 84, 9, 76, 87

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

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 9 is 3 x 3

Prime Factorization of 76 is 2 x 2 x 19

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(84, 9) = 252

GCD(84, 9) = ( 84 x 9 ) / 252

GCD(84, 9) = 756 / 252

GCD(84, 9) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 76

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

LCM(3, 76) = 228

GCD(3, 76) = ( 3 x 76 ) / 228

GCD(3, 76) = 228 / 228

GCD(3, 76) = 1

Step3:

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 84, 9, 76, 87 is 1
