Greatest Common Divisior
We found the divisors of 243, 985, 623, 720 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 243, 985, 623, 720 is 1.
Therefore, GCD of numbers 243, 985, 623, 720 is 1
Given Input Data is 243, 985, 623, 720
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3
Prime Factorization of 985 is 5 x 197
Prime Factorization of 623 is 7 x 89
Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5
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(243, 985) = 239355
GCD(243, 985) = ( 243 x 985 ) / 239355
GCD(243, 985) = 239355 / 239355
GCD(243, 985) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 623
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 623) = 623
GCD(1, 623) = ( 1 x 623 ) / 623
GCD(1, 623) = 623 / 623
GCD(1, 623) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 720
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
GCD(1, 720) = 720 / 720
GCD(1, 720) = 1
GCD of 243, 985, 623, 720 is 1
