Make use of GCD Calculator to determine the Greatest Common Divisor of 813, 855, 72, 479 i.e. 1 largest integer that divides all the numbers equally.
GCD of 813, 855, 72, 479 is 1
GCD(813, 855, 72, 479) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 813, 855, 72, 479 is 1
GCD(813, 855, 72, 479) = 1
Given Input numbers are 813, 855, 72, 479
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 813

1, 479
Greatest Common Divisior
We found the divisors of 813, 855, 72, 479 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 813, 855, 72, 479 is 1.
Therefore, GCD of numbers 813, 855, 72, 479 is 1
Given Input Data is 813, 855, 72, 479
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 813 is 3 x 271
Prime Factorization of 855 is 3 x 3 x 5 x 19
Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3
Prime Factorization of 479 is 479
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(813, 855) = 231705
GCD(813, 855) = ( 813 x 855 ) / 231705
GCD(813, 855) = 695115 / 231705
GCD(813, 855) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 72
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 72) = 72
GCD(3, 72) = ( 3 x 72 ) / 72
GCD(3, 72) = 216 / 72
GCD(3, 72) = 3
Step3:
Here we consider the GCD from the above i.e. 3 as first number and the next as 479
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 479) = 1437
GCD(3, 479) = ( 3 x 479 ) / 1437
GCD(3, 479) = 1437 / 1437
GCD(3, 479) = 1
GCD of 813, 855, 72, 479 is 1
