Given numbers are 858, 406, 273, 815

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 273 are 3 x 7 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 858, 406, 273, 815

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, 273) = 546

GCD(2, 273) = ( 2 x 273 ) / 546

= 2 / 273

= 2

Step3:

LCM(1, 815) = 815

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

= 1 / 815

= 1

So, Greatest Common Divisor of 858, 406, 273, 815 is 1
