Given numbers are 399, 626, 660, 459

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 626 are 2 x 313

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 459 are 3 x 3 x 3 x 17

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 399, 626, 660, 459

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(399, 626) = 249774

GCD(399, 626) = ( 399 x 626 ) / 249774

= 399 / 626

= 399

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1

So, Greatest Common Divisor of 399, 626, 660, 459 is 1
