Given numbers are 474, 390, 991, 630

The list of prime factors of all numbers are

Prime factors of 474 are 2 x 3 x 79

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

Prime factors of 991 are 991

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

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

Given numbers are 474, 390, 991, 630

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

Apply this formula for all numbers.

Step1:

LCM(474, 390) = 30810

GCD(474, 390) = ( 474 x 390 ) / 30810

= 474 / 390

= 474

Step2:

LCM(6, 991) = 5946

GCD(6, 991) = ( 6 x 991 ) / 5946

= 6 / 991

= 6

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 474, 390, 991, 630 is 1
