Greatest Common Divisior
We found the divisors of 646, 766, 530, 279 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 646, 766, 530, 279 is 1.
Therefore, GCD of numbers 646, 766, 530, 279 is 1
Given Input Data is 646, 766, 530, 279
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 646 is 2 x 17 x 19
Prime Factorization of 766 is 2 x 383
Prime Factorization of 530 is 2 x 5 x 53
Prime Factorization of 279 is 3 x 3 x 31
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(646, 766) = 247418
GCD(646, 766) = ( 646 x 766 ) / 247418
GCD(646, 766) = 494836 / 247418
GCD(646, 766) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 530
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 530) = 530
GCD(2, 530) = ( 2 x 530 ) / 530
GCD(2, 530) = 1060 / 530
GCD(2, 530) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 279
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 279) = 558
GCD(2, 279) = ( 2 x 279 ) / 558
GCD(2, 279) = 558 / 558
GCD(2, 279) = 1
GCD of 646, 766, 530, 279 is 1
