1, 2, 197, 394
Greatest Common Divisior
We found the divisors of 399, 128, 32, 394 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 399, 128, 32, 394 is 1.
Therefore, GCD of numbers 399, 128, 32, 394 is 1
Given Input Data is 399, 128, 32, 394
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 399 is 3 x 7 x 19
Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 32 is 2 x 2 x 2 x 2 x 2
Prime Factorization of 394 is 2 x 197
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(399, 128) = 51072
GCD(399, 128) = ( 399 x 128 ) / 51072
GCD(399, 128) = 51072 / 51072
GCD(399, 128) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 32
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 32) = 32
GCD(1, 32) = ( 1 x 32 ) / 32
GCD(1, 32) = 32 / 32
GCD(1, 32) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 394
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
GCD(1, 394) = 394 / 394
GCD(1, 394) = 1
GCD of 399, 128, 32, 394 is 1
