Greatest Common Divisior
We found the divisors of 530, 398, 79, 668 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 530, 398, 79, 668 is 1.
Therefore, GCD of numbers 530, 398, 79, 668 is 1
Given Input Data is 530, 398, 79, 668
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 530 is 2 x 5 x 53
Prime Factorization of 398 is 2 x 199
Prime Factorization of 79 is 79
Prime Factorization of 668 is 2 x 2 x 167
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(530, 398) = 105470
GCD(530, 398) = ( 530 x 398 ) / 105470
GCD(530, 398) = 210940 / 105470
GCD(530, 398) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 79
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 79) = 158
GCD(2, 79) = ( 2 x 79 ) / 158
GCD(2, 79) = 158 / 158
GCD(2, 79) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 668
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
GCD(1, 668) = 668 / 668
GCD(1, 668) = 1
GCD of 530, 398, 79, 668 is 1
