Given numbers are 858, 813, 510, 515

The list of prime factors of all numbers are

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

Prime factors of 813 are 3 x 271

Prime factors of 510 are 2 x 3 x 5 x 17

Prime factors of 515 are 5 x 103

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

Given numbers are 858, 813, 510, 515

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

Apply this formula for all numbers.

Step1:

LCM(858, 813) = 232518

GCD(858, 813) = ( 858 x 813 ) / 232518

= 858 / 813

= 858

Step2:

LCM(3, 510) = 510

GCD(3, 510) = ( 3 x 510 ) / 510

= 3 / 510

= 3

Step3:

LCM(3, 515) = 1545

GCD(3, 515) = ( 3 x 515 ) / 1545

= 3 / 515

= 3

So, Greatest Common Divisor of 858, 813, 510, 515 is 1
