Given numbers are 340, 165, 520, 399

The list of prime factors of all numbers are

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 165 are 3 x 5 x 11

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

Prime factors of 399 are 3 x 7 x 19

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

Given numbers are 340, 165, 520, 399

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

Apply this formula for all numbers.

Step1:

LCM(340, 165) = 11220

GCD(340, 165) = ( 340 x 165 ) / 11220

= 340 / 165

= 340

Step2:

LCM(5, 520) = 520

GCD(5, 520) = ( 5 x 520 ) / 520

= 5 / 520

= 5

Step3:

LCM(5, 399) = 1995

GCD(5, 399) = ( 5 x 399 ) / 1995

= 5 / 399

= 5

So, Greatest Common Divisor of 340, 165, 520, 399 is 1
