Given numbers are 858, 406, 835, 813

The list of prime factors of all numbers are

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

Prime factors of 406 are 2 x 7 x 29

Prime factors of 835 are 5 x 167

Prime factors of 813 are 3 x 271

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

Given numbers are 858, 406, 835, 813

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

Apply this formula for all numbers.

Step1:

LCM(858, 406) = 174174

GCD(858, 406) = ( 858 x 406 ) / 174174

= 858 / 406

= 858

Step2:

LCM(2, 835) = 1670

GCD(2, 835) = ( 2 x 835 ) / 1670

= 2 / 835

= 2

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 858, 406, 835, 813 is 1
