Make use of GCD Calculator to determine the Greatest Common Divisor of 637, 215, 68 i.e. 1 largest integer that divides all the numbers equally.
GCD of 637, 215, 68 is 1
GCD(637, 215, 68) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 637, 215, 68 is 1
GCD(637, 215, 68) = 1
Given Input numbers are 637, 215, 68
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 43, 215
Divisors of 68
List of positive integer divisors of 68 that divides 68 without a remainder.
1, 2, 4, 17, 34, 68
Greatest Common Divisior
We found the divisors of 637, 215, 68 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 637, 215, 68 is 1.
Therefore, GCD of numbers 637, 215, 68 is 1
Given Input Data is 637, 215, 68
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 637 is 7 x 7 x 13
Prime Factorization of 215 is 5 x 43
Prime Factorization of 68 is 2 x 2 x 17
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(637, 215) = 136955
GCD(637, 215) = ( 637 x 215 ) / 136955
GCD(637, 215) = 136955 / 136955
GCD(637, 215) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 68
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
GCD(1, 68) = 68 / 68
GCD(1, 68) = 1
GCD of 637, 215, 68 is 1
