Greatest Common Divisior
We found the divisors of 664, 919, 81, 403 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 664, 919, 81, 403 is 1.
Therefore, GCD of numbers 664, 919, 81, 403 is 1
Given Input Data is 664, 919, 81, 403
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 664 is 2 x 2 x 2 x 83
Prime Factorization of 919 is 919
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 403 is 13 x 31
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(664, 919) = 610216
GCD(664, 919) = ( 664 x 919 ) / 610216
GCD(664, 919) = 610216 / 610216
GCD(664, 919) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 81
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
GCD(1, 81) = 81 / 81
GCD(1, 81) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 403
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
GCD(1, 403) = 403 / 403
GCD(1, 403) = 1
GCD of 664, 919, 81, 403 is 1
