Greatest Common Divisior
We found the divisors of 128, 295, 443, 647 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 128, 295, 443, 647 is 1.
Therefore, GCD of numbers 128, 295, 443, 647 is 1
Given Input Data is 128, 295, 443, 647
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 295 is 5 x 59
Prime Factorization of 443 is 443
Prime Factorization of 647 is 647
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(128, 295) = 37760
GCD(128, 295) = ( 128 x 295 ) / 37760
GCD(128, 295) = 37760 / 37760
GCD(128, 295) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 443
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 443) = 443
GCD(1, 443) = ( 1 x 443 ) / 443
GCD(1, 443) = 443 / 443
GCD(1, 443) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 647
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
GCD(1, 647) = 647 / 647
GCD(1, 647) = 1
GCD of 128, 295, 443, 647 is 1
