The list of prime factors of all numbers are

Prime factors of 817 are 19 x 43

Prime factors of 921 are 3 x 307

Prime factors of 805 are 5 x 7 x 23

Prime factors of 611 are 13 x 47

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

Given numbers are 817, 921, 805, 611

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

Apply this formula for all numbers.

Step1:

LCM(817, 921) = 752457

GCD(817, 921) = ( 817 x 921 ) / 752457

= 817 / 921

= 817

Step2:

LCM(1, 805) = 805

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

= 1 / 805

= 1

Step3:

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

= 1 / 611

= 1

So, Greatest Common Divisor of 817, 921, 805, 611 is 1
