The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 354 are 2 x 3 x 59

Prime factors of 909 are 3 x 3 x 101

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 399, 354, 909, 520

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

Apply this formula for all numbers.

Step1:

LCM(399, 354) = 47082

GCD(399, 354) = ( 399 x 354 ) / 47082

= 399 / 354

= 399

Step2:

LCM(3, 909) = 909

GCD(3, 909) = ( 3 x 909 ) / 909

= 3 / 909

= 3

Step3:

LCM(3, 520) = 1560

GCD(3, 520) = ( 3 x 520 ) / 1560

= 3 / 520

= 3

So, Greatest Common Divisor of 399, 354, 909, 520 is 1
