Given numbers are 817, 213, 854, 805

The list of prime factors of all numbers are

Prime factors of 817 are 19 x 43

Prime factors of 213 are 3 x 71

Prime factors of 854 are 2 x 7 x 61

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 817, 213, 854, 805

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

Apply this formula for all numbers.

Step1:

LCM(817, 213) = 174021

GCD(817, 213) = ( 817 x 213 ) / 174021

= 817 / 213

= 817

Step2:

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

= 1 / 854

= 1

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 817, 213, 854, 805 is 1
