Given numbers are 710, 309, 858, 815

The list of prime factors of all numbers are

Prime factors of 710 are 2 x 5 x 71

Prime factors of 309 are 3 x 103

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 815 are 5 x 163

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

Given numbers are 710, 309, 858, 815

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

Apply this formula for all numbers.

Step1:

LCM(710, 309) = 219390

GCD(710, 309) = ( 710 x 309 ) / 219390

= 710 / 309

= 710

Step2:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 710, 309, 858, 815 is 1
