We found the divisors of 81, 87, 46 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 81, 87, 46 is 1.

Therefore, GCD of numbers 81, 87, 46 is 1

Given Input Data is 81, 87, 46

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

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 87 is 3 x 29

Prime Factorization of 46 is 2 x 23

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(81, 87) = 2349

GCD(81, 87) = ( 81 x 87 ) / 2349

GCD(81, 87) = 7047 / 2349

GCD(81, 87) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 46

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

LCM(3, 46) = 138

GCD(3, 46) = ( 3 x 46 ) / 138

GCD(3, 46) = 138 / 138

GCD(3, 46) = 1

GCD of 81, 87, 46 is 1
