Given numbers are 805, 399, 500, 630

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 399 are 3 x 7 x 19

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

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

Given numbers are 805, 399, 500, 630

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

Apply this formula for all numbers.

Step1:

LCM(805, 399) = 45885

GCD(805, 399) = ( 805 x 399 ) / 45885

= 805 / 399

= 805

Step2:

LCM(7, 500) = 3500

GCD(7, 500) = ( 7 x 500 ) / 3500

= 7 / 500

= 7

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 805, 399, 500, 630 is 1
