Make use of GCD Calculator to determine the Greatest Common Divisor of 656, 618, 637 i.e. 1 largest integer that divides all the numbers equally.
GCD of 656, 618, 637 is 1
GCD(656, 618, 637) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 656, 618, 637 is 1
GCD(656, 618, 637) = 1
Given Input numbers are 656, 618, 637
To find the GCD of numbers using factoring list out all the divisors of each number

1, 7, 13, 49, 91, 637
Greatest Common Divisior
We found the divisors of 656, 618, 637 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 656, 618, 637 is 1.
Therefore, GCD of numbers 656, 618, 637 is 1
Given Input Data is 656, 618, 637
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41
Prime Factorization of 618 is 2 x 3 x 103
Prime Factorization of 637 is 7 x 7 x 13
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(656, 618) = 202704
GCD(656, 618) = ( 656 x 618 ) / 202704
GCD(656, 618) = 405408 / 202704
GCD(656, 618) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 637
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 637) = 1274
GCD(2, 637) = ( 2 x 637 ) / 1274
GCD(2, 637) = 1274 / 1274
GCD(2, 637) = 1
GCD of 656, 618, 637 is 1
