Therefore, GCD of numbers 399, 651, 14, 325 is 1

Given Input Data is 399, 651, 14, 325

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 651 is 3 x 7 x 31

Prime Factorization of 14 is 2 x 7

Prime Factorization of 325 is 5 x 5 x 13

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, 651) = 12369

GCD(399, 651) = ( 399 x 651 ) / 12369

GCD(399, 651) = 259749 / 12369

GCD(399, 651) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 14

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

LCM(21, 14) = 42

GCD(21, 14) = ( 21 x 14 ) / 42

GCD(21, 14) = 294 / 42

GCD(21, 14) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 325

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

LCM(7, 325) = 2275

GCD(7, 325) = ( 7 x 325 ) / 2275

GCD(7, 325) = 2275 / 2275

GCD(7, 325) = 1

GCD of 399, 651, 14, 325 is 1
