Greatest Common Divisior
We found the divisors of 591, 906, 28, 405 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 591, 906, 28, 405 is 1.
Therefore, GCD of numbers 591, 906, 28, 405 is 1
Given Input Data is 591, 906, 28, 405
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 591 is 3 x 197
Prime Factorization of 906 is 2 x 3 x 151
Prime Factorization of 28 is 2 x 2 x 7
Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5
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(591, 906) = 178482
GCD(591, 906) = ( 591 x 906 ) / 178482
GCD(591, 906) = 535446 / 178482
GCD(591, 906) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 28
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 28) = 84
GCD(3, 28) = ( 3 x 28 ) / 84
GCD(3, 28) = 84 / 84
GCD(3, 28) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 405
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
GCD(1, 405) = 405 / 405
GCD(1, 405) = 1
GCD of 591, 906, 28, 405 is 1
