Make use of GCD Calculator to determine the Greatest Common Divisor of 685, 203, 786, 502 i.e. 1 largest integer that divides all the numbers equally.
GCD of 685, 203, 786, 502 is 1
GCD(685, 203, 786, 502) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 685, 203, 786, 502 is 1
GCD(685, 203, 786, 502) = 1
Given Input numbers are 685, 203, 786, 502
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 251, 502
Greatest Common Divisior
We found the divisors of 685, 203, 786, 502 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 685, 203, 786, 502 is 1.
Therefore, GCD of numbers 685, 203, 786, 502 is 1
Given Input Data is 685, 203, 786, 502
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 685 is 5 x 137
Prime Factorization of 203 is 7 x 29
Prime Factorization of 786 is 2 x 3 x 131
Prime Factorization of 502 is 2 x 251
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(685, 203) = 139055
GCD(685, 203) = ( 685 x 203 ) / 139055
GCD(685, 203) = 139055 / 139055
GCD(685, 203) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 786
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 786) = 786
GCD(1, 786) = ( 1 x 786 ) / 786
GCD(1, 786) = 786 / 786
GCD(1, 786) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 502
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 502) = 502
GCD(1, 502) = ( 1 x 502 ) / 502
GCD(1, 502) = 502 / 502
GCD(1, 502) = 1
GCD of 685, 203, 786, 502 is 1
