1, 17, 37, 629
Greatest Common Divisior
We found the divisors of 717, 861, 478, 629 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 717, 861, 478, 629 is 1.
Therefore, GCD of numbers 717, 861, 478, 629 is 1
Given Input Data is 717, 861, 478, 629
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 717 is 3 x 239
Prime Factorization of 861 is 3 x 7 x 41
Prime Factorization of 478 is 2 x 239
Prime Factorization of 629 is 17 x 37
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(717, 861) = 205779
GCD(717, 861) = ( 717 x 861 ) / 205779
GCD(717, 861) = 617337 / 205779
GCD(717, 861) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 478
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 478) = 1434
GCD(3, 478) = ( 3 x 478 ) / 1434
GCD(3, 478) = 1434 / 1434
GCD(3, 478) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 629
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 629) = 629
GCD(1, 629) = ( 1 x 629 ) / 629
GCD(1, 629) = 629 / 629
GCD(1, 629) = 1
GCD of 717, 861, 478, 629 is 1
