Make use of GCD Calculator to determine the Greatest Common Divisor of 18, 6, 81, 95 i.e. 1 largest integer that divides all the numbers equally.
GCD of 18, 6, 81, 95 is 1
GCD(18, 6, 81, 95) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 18, 6, 81, 95 is 1
GCD(18, 6, 81, 95) = 1
Given Input numbers are 18, 6, 81, 95
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 18
List of positive integer divisors of 18 that divides 18 without a remainder.
1, 2, 3, 6, 9, 18
Divisors of 6

1, 2, 3, 6
Divisors of 81
List of positive integer divisors of 81 that divides 81 without a remainder.
1, 3, 9, 27, 81
Divisors of 95
List of positive integer divisors of 95 that divides 95 without a remainder.
1, 5, 19, 95
Greatest Common Divisior
We found the divisors of 18, 6, 81, 95 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 18, 6, 81, 95 is 1.
Therefore, GCD of numbers 18, 6, 81, 95 is 1
Given Input Data is 18, 6, 81, 95
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 18 is 2 x 3 x 3
Prime Factorization of 6 is 2 x 3
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 95 is 5 x 19
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(18, 6) = 18
GCD(18, 6) = ( 18 x 6 ) / 18
GCD(18, 6) = 108 / 18
GCD(18, 6) = 6
Step2:
Here we consider the GCD from the above i.e. 6 as first number and the next as 81
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 81) = 162
GCD(6, 81) = ( 6 x 81 ) / 162
GCD(6, 81) = 486 / 162
GCD(6, 81) = 3
Step3:
Here we consider the GCD from the above i.e. 3 as first number and the next as 95
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 95) = 285
GCD(3, 95) = ( 3 x 95 ) / 285
GCD(3, 95) = 285 / 285
GCD(3, 95) = 1
GCD of 18, 6, 81, 95 is 1
