Given numbers are 390, 636, 495, 310

The list of prime factors of all numbers are

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

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 310 are 2 x 5 x 31

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

Given numbers are 390, 636, 495, 310

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

Apply this formula for all numbers.

Step1:

LCM(390, 636) = 41340

GCD(390, 636) = ( 390 x 636 ) / 41340

= 390 / 636

= 390

Step2:

LCM(6, 495) = 990

GCD(6, 495) = ( 6 x 495 ) / 990

= 6 / 495

= 6

Step3:

LCM(3, 310) = 930

GCD(3, 310) = ( 3 x 310 ) / 930

= 3 / 310

= 3

So, Greatest Common Divisor of 390, 636, 495, 310 is 1
