Greatest Common Divisior
We found the divisors of 643, 336, 676, 978 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 643, 336, 676, 978 is 1.
Therefore, GCD of numbers 643, 336, 676, 978 is 1
Given Input Data is 643, 336, 676, 978
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 643 is 643
Prime Factorization of 336 is 2 x 2 x 2 x 2 x 3 x 7
Prime Factorization of 676 is 2 x 2 x 13 x 13
Prime Factorization of 978 is 2 x 3 x 163
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(643, 336) = 216048
GCD(643, 336) = ( 643 x 336 ) / 216048
GCD(643, 336) = 216048 / 216048
GCD(643, 336) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 676
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 676) = 676
GCD(1, 676) = ( 1 x 676 ) / 676
GCD(1, 676) = 676 / 676
GCD(1, 676) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 978
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
GCD(1, 978) = 978 / 978
GCD(1, 978) = 1
GCD of 643, 336, 676, 978 is 1
