Given numbers are 402, 516, 313, 390

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 313 are 313

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 402, 516, 313, 390

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

Apply this formula for all numbers.

Step1:

LCM(402, 516) = 34572

GCD(402, 516) = ( 402 x 516 ) / 34572

= 402 / 516

= 402

Step2:

LCM(6, 313) = 1878

GCD(6, 313) = ( 6 x 313 ) / 1878

= 6 / 313

= 6

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 402, 516, 313, 390 is 1
