Therefore, GCD of numbers 28, 329, 624, 107 is 1

Given Input Data is 28, 329, 624, 107

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 329 is 7 x 47

Prime Factorization of 624 is 2 x 2 x 2 x 2 x 3 x 13

Prime Factorization of 107 is 107

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(28, 329) = 1316

GCD(28, 329) = ( 28 x 329 ) / 1316

GCD(28, 329) = 9212 / 1316

GCD(28, 329) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 624

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

LCM(7, 624) = 4368

GCD(7, 624) = ( 7 x 624 ) / 4368

GCD(7, 624) = 4368 / 4368

GCD(7, 624) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 107

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

LCM(1, 107) = 107

GCD(1, 107) = ( 1 x 107 ) / 107

GCD(1, 107) = 107 / 107

GCD(1, 107) = 1

GCD of 28, 329, 624, 107 is 1
