Given numbers are 630, 310, 195, 403

The list of prime factors of all numbers are

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 310 are 2 x 5 x 31

Prime factors of 195 are 3 x 5 x 13

Prime factors of 403 are 13 x 31

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

Given numbers are 630, 310, 195, 403

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

Apply this formula for all numbers.

Step1:

LCM(630, 310) = 19530

GCD(630, 310) = ( 630 x 310 ) / 19530

= 630 / 310

= 630

Step2:

LCM(10, 195) = 390

GCD(10, 195) = ( 10 x 195 ) / 390

= 10 / 195

= 10

Step3:

LCM(5, 403) = 2015

GCD(5, 403) = ( 5 x 403 ) / 2015

= 5 / 403

= 5

So, Greatest Common Divisor of 630, 310, 195, 403 is 1
