Make use of GCD Calculator to determine the Greatest Common Divisor of 326, 430, 81, 240 i.e. 1 largest integer that divides all the numbers equally.
GCD of 326, 430, 81, 240 is 1
GCD(326, 430, 81, 240) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 326, 430, 81, 240 is 1
GCD(326, 430, 81, 240) = 1
Given Input numbers are 326, 430, 81, 240
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 326

1, 3, 9, 27, 81
Divisors of 240
List of positive integer divisors of 240 that divides 240 without a remainder.
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
Greatest Common Divisior
We found the divisors of 326, 430, 81, 240 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 326, 430, 81, 240 is 1.
Therefore, GCD of numbers 326, 430, 81, 240 is 1
Given Input Data is 326, 430, 81, 240
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 326 is 2 x 163
Prime Factorization of 430 is 2 x 5 x 43
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 240 is 2 x 2 x 2 x 2 x 3 x 5
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(326, 430) = 70090
GCD(326, 430) = ( 326 x 430 ) / 70090
GCD(326, 430) = 140180 / 70090
GCD(326, 430) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 81
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 81) = 162
GCD(2, 81) = ( 2 x 81 ) / 162
GCD(2, 81) = 162 / 162
GCD(2, 81) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 240
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 240) = 240
GCD(1, 240) = ( 1 x 240 ) / 240
GCD(1, 240) = 240 / 240
GCD(1, 240) = 1
GCD of 326, 430, 81, 240 is 1
