Make use of GCD Calculator to determine the Greatest Common Divisor of 501, 340, 18, 686 i.e. 1 largest integer that divides all the numbers equally.
GCD of 501, 340, 18, 686 is 1
GCD(501, 340, 18, 686) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 501, 340, 18, 686 is 1
GCD(501, 340, 18, 686) = 1
Given Input numbers are 501, 340, 18, 686
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 3, 6, 9, 18
Divisors of 686
List of positive integer divisors of 686 that divides 686 without a remainder.
1, 2, 7, 14, 49, 98, 343, 686
Greatest Common Divisior
We found the divisors of 501, 340, 18, 686 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 501, 340, 18, 686 is 1.
Therefore, GCD of numbers 501, 340, 18, 686 is 1
Given Input Data is 501, 340, 18, 686
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 501 is 3 x 167
Prime Factorization of 340 is 2 x 2 x 5 x 17
Prime Factorization of 18 is 2 x 3 x 3
Prime Factorization of 686 is 2 x 7 x 7 x 7
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(501, 340) = 170340
GCD(501, 340) = ( 501 x 340 ) / 170340
GCD(501, 340) = 170340 / 170340
GCD(501, 340) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 18
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 18) = 18
GCD(1, 18) = ( 1 x 18 ) / 18
GCD(1, 18) = 18 / 18
GCD(1, 18) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 686
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
GCD(1, 686) = 686 / 686
GCD(1, 686) = 1
GCD of 501, 340, 18, 686 is 1
