The list of prime factors of all numbers are

Prime factors of 817 are 19 x 43

Prime factors of 206 are 2 x 103

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 221 are 13 x 17

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

Given numbers are 817, 206, 550, 221

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

Apply this formula for all numbers.

Step1:

LCM(817, 206) = 168302

GCD(817, 206) = ( 817 x 206 ) / 168302

= 817 / 206

= 817

Step2:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 817, 206, 550, 221 is 1
