Given numbers are 630, 390, 798, 671

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 390 are 2 x 3 x 5 x 13

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 671 are 11 x 61

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

Given numbers are 630, 390, 798, 671

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

Apply this formula for all numbers.

Step1:

LCM(630, 390) = 8190

GCD(630, 390) = ( 630 x 390 ) / 8190

= 630 / 390

= 630

Step2:

LCM(30, 798) = 3990

GCD(30, 798) = ( 30 x 798 ) / 3990

= 30 / 798

= 30

Step3:

LCM(6, 671) = 4026

GCD(6, 671) = ( 6 x 671 ) / 4026

= 6 / 671

= 6

So, Greatest Common Divisor of 630, 390, 798, 671 is 1
