Given numbers are 809, 500, 630, 991

The list of prime factors of all numbers are

Prime factors of 809 are 809

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

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

Prime factors of 991 are 991

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

Given numbers are 809, 500, 630, 991

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

Apply this formula for all numbers.

Step1:

LCM(809, 500) = 404500

GCD(809, 500) = ( 809 x 500 ) / 404500

= 809 / 500

= 809

Step2:

LCM(1, 630) = 630

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

= 1 / 630

= 1

Step3:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

So, Greatest Common Divisor of 809, 500, 630, 991 is 1
