We found the divisors of 321, 344, 145 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 321, 344, 145 is 1.

Therefore, GCD of numbers 321, 344, 145 is 1

Given Input Data is 321, 344, 145

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 321 is 3 x 107

Prime Factorization of 344 is 2 x 2 x 2 x 43

Prime Factorization of 145 is 5 x 29

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(321, 344) = 110424

GCD(321, 344) = ( 321 x 344 ) / 110424

GCD(321, 344) = 110424 / 110424

GCD(321, 344) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 145

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

GCD(1, 145) = 145 / 145

GCD(1, 145) = 1

GCD of 321, 344, 145 is 1
