Make use of GCD Calculator to determine the Greatest Common Divisor of 89, 18, 81 i.e. 1 largest integer that divides all the numbers equally.
GCD of 89, 18, 81 is 1
GCD(89, 18, 81) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 89, 18, 81 is 1
GCD(89, 18, 81) = 1
Given Input numbers are 89, 18, 81
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 89

1, 89
Divisors of 18
List of positive integer divisors of 18 that divides 18 without a remainder.
1, 2, 3, 6, 9, 18
Divisors of 81
List of positive integer divisors of 81 that divides 81 without a remainder.
1, 3, 9, 27, 81
Greatest Common Divisior
We found the divisors of 89, 18, 81 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 89, 18, 81 is 1.
Therefore, GCD of numbers 89, 18, 81 is 1
Given Input Data is 89, 18, 81
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 89 is 89
Prime Factorization of 18 is 2 x 3 x 3
Prime Factorization of 81 is 3 x 3 x 3 x 3
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(89, 18) = 1602
GCD(89, 18) = ( 89 x 18 ) / 1602
GCD(89, 18) = 1602 / 1602
GCD(89, 18) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 81
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
GCD(1, 81) = 81 / 81
GCD(1, 81) = 1
GCD of 89, 18, 81 is 1
