Given numbers are 870, 819, 469, 309

The list of prime factors of all numbers are

Prime factors of 870 are 2 x 3 x 5 x 29

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

Prime factors of 469 are 7 x 67

Prime factors of 309 are 3 x 103

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

Given numbers are 870, 819, 469, 309

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

Apply this formula for all numbers.

Step1:

LCM(870, 819) = 237510

GCD(870, 819) = ( 870 x 819 ) / 237510

= 870 / 819

= 870

Step2:

LCM(3, 469) = 1407

GCD(3, 469) = ( 3 x 469 ) / 1407

= 3 / 469

= 3

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 870, 819, 469, 309 is 1
