Make use of GCD Calculator to determine the Greatest Common Divisor of 36, 12, 81 i.e. 3 largest integer that divides all the numbers equally.
GCD of 36, 12, 81 is 3
GCD(36, 12, 81) = 3
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 36, 12, 81 is 3
GCD(36, 12, 81) = 3
Given Input numbers are 36, 12, 81
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 36
List of positive integer divisors of 36 that divides 36 without a remainder.
1, 2, 3, 4, 6, 9, 12, 18, 36
Divisors of 12
List of positive integer divisors of 12 that divides 12 without a remainder.
1, 2, 3, 4, 6, 12
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 36, 12, 81 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 36, 12, 81 is 3.
Therefore, GCD of numbers 36, 12, 81 is 3
Given Input Data is 36, 12, 81
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 36 is 2 x 2 x 3 x 3
Prime Factorization of 12 is 2 x 2 x 3
Prime Factorization of 81 is 3 x 3 x 3 x 3
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(36, 12) = 36
GCD(36, 12) = ( 36 x 12 ) / 36
GCD(36, 12) = 432 / 36
GCD(36, 12) = 12
Step2:
Here we consider the GCD from the above i.e. 12 as first number and the next as 81
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(12, 81) = 324
GCD(12, 81) = ( 12 x 81 ) / 324
GCD(12, 81) = 972 / 324
GCD(12, 81) = 3
GCD of 36, 12, 81 is 3
