Greatest Common Divisior
We found the divisors of 643, 999, 42, 718 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 643, 999, 42, 718 is 1.
Therefore, GCD of numbers 643, 999, 42, 718 is 1
Given Input Data is 643, 999, 42, 718
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 643 is 643
Prime Factorization of 999 is 3 x 3 x 3 x 37
Prime Factorization of 42 is 2 x 3 x 7
Prime Factorization of 718 is 2 x 359
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, 999) = 642357
GCD(643, 999) = ( 643 x 999 ) / 642357
GCD(643, 999) = 642357 / 642357
GCD(643, 999) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 42
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
GCD(1, 42) = 42 / 42
GCD(1, 42) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 718
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 718) = 718
GCD(1, 718) = ( 1 x 718 ) / 718
GCD(1, 718) = 718 / 718
GCD(1, 718) = 1
GCD of 643, 999, 42, 718 is 1
