Greatest Common Divisior
We found the divisors of 639, 322, 33, 868 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 639, 322, 33, 868 is 1.
Therefore, GCD of numbers 639, 322, 33, 868 is 1
Given Input Data is 639, 322, 33, 868
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 639 is 3 x 3 x 71
Prime Factorization of 322 is 2 x 7 x 23
Prime Factorization of 33 is 3 x 11
Prime Factorization of 868 is 2 x 2 x 7 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(639, 322) = 205758
GCD(639, 322) = ( 639 x 322 ) / 205758
GCD(639, 322) = 205758 / 205758
GCD(639, 322) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 33
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 33) = 33
GCD(1, 33) = ( 1 x 33 ) / 33
GCD(1, 33) = 33 / 33
GCD(1, 33) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 868
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
GCD(1, 868) = 868 / 868
GCD(1, 868) = 1
GCD of 639, 322, 33, 868 is 1
