Given numbers are 210, 819, 363, 686

The list of prime factors of all numbers are

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 363 are 3 x 11 x 11

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 210, 819, 363, 686

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

Apply this formula for all numbers.

Step1:

LCM(210, 819) = 8190

GCD(210, 819) = ( 210 x 819 ) / 8190

= 210 / 819

= 210

Step2:

LCM(21, 363) = 2541

GCD(21, 363) = ( 21 x 363 ) / 2541

= 21 / 363

= 21

Step3:

LCM(3, 686) = 2058

GCD(3, 686) = ( 3 x 686 ) / 2058

= 3 / 686

= 3

So, Greatest Common Divisor of 210, 819, 363, 686 is 1
