Greatest Common Divisior
We found the divisors of 646, 876, 20, 483 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 646, 876, 20, 483 is 1.
Therefore, GCD of numbers 646, 876, 20, 483 is 1
Given Input Data is 646, 876, 20, 483
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 646 is 2 x 17 x 19
Prime Factorization of 876 is 2 x 2 x 3 x 73
Prime Factorization of 20 is 2 x 2 x 5
Prime Factorization of 483 is 3 x 7 x 23
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(646, 876) = 282948
GCD(646, 876) = ( 646 x 876 ) / 282948
GCD(646, 876) = 565896 / 282948
GCD(646, 876) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 20
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 20) = 20
GCD(2, 20) = ( 2 x 20 ) / 20
GCD(2, 20) = 40 / 20
GCD(2, 20) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 483
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 483) = 966
GCD(2, 483) = ( 2 x 483 ) / 966
GCD(2, 483) = 966 / 966
GCD(2, 483) = 1
GCD of 646, 876, 20, 483 is 1
