Given numbers are 858, 161, 513, 806

The list of prime factors of all numbers are

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

Prime factors of 161 are 7 x 23

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 806 are 2 x 13 x 31

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

Given numbers are 858, 161, 513, 806

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

Apply this formula for all numbers.

Step1:

LCM(858, 161) = 138138

GCD(858, 161) = ( 858 x 161 ) / 138138

= 858 / 161

= 858

Step2:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

Step3:

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

= 1 / 806

= 1

So, Greatest Common Divisor of 858, 161, 513, 806 is 1
