We found the divisors of 9, 81, 66 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 9, 81, 66 is 3.

Therefore, GCD of numbers 9, 81, 66 is 3

Given Input Data is 9, 81, 66

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

Prime Factorization of 9 is 3 x 3

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

Prime Factorization of 66 is 2 x 3 x 11

Highest common occurrences in the given inputs are 3¹

Multiplying them we get the GCD as 3

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(9, 81) = 81

GCD(9, 81) = ( 9 x 81 ) / 81

GCD(9, 81) = 729 / 81

GCD(9, 81) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 66

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

LCM(9, 66) = 198

GCD(9, 66) = ( 9 x 66 ) / 198

GCD(9, 66) = 594 / 198

GCD(9, 66) = 3

GCD of 9, 81, 66 is 3
