Greatest Common Divisior
We found the divisors of 631, 646, 389, 169 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 631, 646, 389, 169 is 1.
Therefore, GCD of numbers 631, 646, 389, 169 is 1
Given Input Data is 631, 646, 389, 169
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 631 is 631
Prime Factorization of 646 is 2 x 17 x 19
Prime Factorization of 389 is 389
Prime Factorization of 169 is 13 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(631, 646) = 407626
GCD(631, 646) = ( 631 x 646 ) / 407626
GCD(631, 646) = 407626 / 407626
GCD(631, 646) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 389
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
GCD(1, 389) = 389 / 389
GCD(1, 389) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 169
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 169) = 169
GCD(1, 169) = ( 1 x 169 ) / 169
GCD(1, 169) = 169 / 169
GCD(1, 169) = 1
GCD of 631, 646, 389, 169 is 1
