We found the divisors of 87, 99, 64 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 87, 99, 64 is 1.

Therefore, GCD of numbers 87, 99, 64 is 1

Given Input Data is 87, 99, 64

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

Prime Factorization of 87 is 3 x 29

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

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, 99) = 2871

GCD(87, 99) = ( 87 x 99 ) / 2871

GCD(87, 99) = 8613 / 2871

GCD(87, 99) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 64

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

LCM(3, 64) = 192

GCD(3, 64) = ( 3 x 64 ) / 192

GCD(3, 64) = 192 / 192

GCD(3, 64) = 1

GCD of 87, 99, 64 is 1
