Given numbers are 817, 780, 565, 320

The list of prime factors of all numbers are

Prime factors of 817 are 19 x 43

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 565 are 5 x 113

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 817, 780, 565, 320

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

Apply this formula for all numbers.

Step1:

LCM(817, 780) = 637260

GCD(817, 780) = ( 817 x 780 ) / 637260

= 817 / 780

= 817

Step2:

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

= 1 / 565

= 1

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 817, 780, 565, 320 is 1
