The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 534 are 2 x 3 x 89

Prime factors of 717 are 3 x 239

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 398, 534, 717, 221

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

Apply this formula for all numbers.

Step1:

LCM(398, 534) = 106266

GCD(398, 534) = ( 398 x 534 ) / 106266

= 398 / 534

= 398

Step2:

LCM(2, 717) = 1434

GCD(2, 717) = ( 2 x 717 ) / 1434

= 2 / 717

= 2

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 398, 534, 717, 221 is 1
