The list of prime factors of all numbers are

Prime factors of 458 are 2 x 229

Prime factors of 745 are 5 x 149

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 817 are 19 x 43

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

Given numbers are 458, 745, 856, 817

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

Apply this formula for all numbers.

Step1:

LCM(458, 745) = 341210

GCD(458, 745) = ( 458 x 745 ) / 341210

= 458 / 745

= 458

Step2:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

Step3:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

So, Greatest Common Divisor of 458, 745, 856, 817 is 1
