Make use of GCD Calculator to determine the Greatest Common Divisor of 520, 817, 20, 836 i.e. 1 largest integer that divides all the numbers equally.
GCD of 520, 817, 20, 836 is 1
GCD(520, 817, 20, 836) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 520, 817, 20, 836 is 1
GCD(520, 817, 20, 836) = 1
Given Input numbers are 520, 817, 20, 836
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
Greatest Common Divisior
We found the divisors of 520, 817, 20, 836 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 520, 817, 20, 836 is 1.
Therefore, GCD of numbers 520, 817, 20, 836 is 1
Given Input Data is 520, 817, 20, 836
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13
Prime Factorization of 817 is 19 x 43
Prime Factorization of 20 is 2 x 2 x 5
Prime Factorization of 836 is 2 x 2 x 11 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(520, 817) = 424840
GCD(520, 817) = ( 520 x 817 ) / 424840
GCD(520, 817) = 424840 / 424840
GCD(520, 817) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 20
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
GCD(1, 20) = 20 / 20
GCD(1, 20) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 836
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 836) = 836
GCD(1, 836) = ( 1 x 836 ) / 836
GCD(1, 836) = 836 / 836
GCD(1, 836) = 1
GCD of 520, 817, 20, 836 is 1
