Greatest Common Divisior
We found the divisors of 647, 970, 656, 449 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 647, 970, 656, 449 is 1.
Therefore, GCD of numbers 647, 970, 656, 449 is 1
Given Input Data is 647, 970, 656, 449
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 647 is 647
Prime Factorization of 970 is 2 x 5 x 97
Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41
Prime Factorization of 449 is 449
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(647, 970) = 627590
GCD(647, 970) = ( 647 x 970 ) / 627590
GCD(647, 970) = 627590 / 627590
GCD(647, 970) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 656
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
GCD(1, 656) = 656 / 656
GCD(1, 656) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 449
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
GCD(1, 449) = 449 / 449
GCD(1, 449) = 1
GCD of 647, 970, 656, 449 is 1
