1, 409
Greatest Common Divisior
We found the divisors of 648, 446, 83, 409 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 648, 446, 83, 409 is 1.
Therefore, GCD of numbers 648, 446, 83, 409 is 1
Given Input Data is 648, 446, 83, 409
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 648 is 2 x 2 x 2 x 3 x 3 x 3 x 3
Prime Factorization of 446 is 2 x 223
Prime Factorization of 83 is 83
Prime Factorization of 409 is 409
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(648, 446) = 144504
GCD(648, 446) = ( 648 x 446 ) / 144504
GCD(648, 446) = 289008 / 144504
GCD(648, 446) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 83
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 83) = 166
GCD(2, 83) = ( 2 x 83 ) / 166
GCD(2, 83) = 166 / 166
GCD(2, 83) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 409
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
GCD(1, 409) = 409 / 409
GCD(1, 409) = 1
GCD of 648, 446, 83, 409 is 1
