Greatest Common Divisior
We found the divisors of 647, 974, 324, 440 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 647, 974, 324, 440 is 1.
Therefore, GCD of numbers 647, 974, 324, 440 is 1
Given Input Data is 647, 974, 324, 440
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 647 is 647
Prime Factorization of 974 is 2 x 487
Prime Factorization of 324 is 2 x 2 x 3 x 3 x 3 x 3
Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11
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, 974) = 630178
GCD(647, 974) = ( 647 x 974 ) / 630178
GCD(647, 974) = 630178 / 630178
GCD(647, 974) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 324
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 324) = 324
GCD(1, 324) = ( 1 x 324 ) / 324
GCD(1, 324) = 324 / 324
GCD(1, 324) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 440
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 440) = 440
GCD(1, 440) = ( 1 x 440 ) / 440
GCD(1, 440) = 440 / 440
GCD(1, 440) = 1
GCD of 647, 974, 324, 440 is 1
