Make use of GCD Calculator to determine the Greatest Common Divisor of 817, 387, 80, 764 i.e. 1 largest integer that divides all the numbers equally.
GCD of 817, 387, 80, 764 is 1
GCD(817, 387, 80, 764) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 817, 387, 80, 764 is 1
GCD(817, 387, 80, 764) = 1
Given Input numbers are 817, 387, 80, 764
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 817

1, 2, 4, 5, 8, 10, 16, 20, 40, 80
Divisors of 764
List of positive integer divisors of 764 that divides 764 without a remainder.
1, 2, 4, 191, 382, 764
Greatest Common Divisior
We found the divisors of 817, 387, 80, 764 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 817, 387, 80, 764 is 1.
Therefore, GCD of numbers 817, 387, 80, 764 is 1
Given Input Data is 817, 387, 80, 764
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 817 is 19 x 43
Prime Factorization of 387 is 3 x 3 x 43
Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5
Prime Factorization of 764 is 2 x 2 x 191
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(817, 387) = 7353
GCD(817, 387) = ( 817 x 387 ) / 7353
GCD(817, 387) = 316179 / 7353
GCD(817, 387) = 43
Step2:
Here we consider the GCD from the above i.e. 43 as first number and the next as 80
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(43, 80) = 3440
GCD(43, 80) = ( 43 x 80 ) / 3440
GCD(43, 80) = 3440 / 3440
GCD(43, 80) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 764
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 764) = 764
GCD(1, 764) = ( 1 x 764 ) / 764
GCD(1, 764) = 764 / 764
GCD(1, 764) = 1
GCD of 817, 387, 80, 764 is 1
