The list of prime factors of all numbers are

Prime factors of 298 are 2 x 149

Prime factors of 830 are 2 x 5 x 83

Prime factors of 808 are 2 x 2 x 2 x 101

Prime factors of 217 are 7 x 31

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

Given numbers are 298, 830, 808, 217

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

Apply this formula for all numbers.

Step1:

LCM(298, 830) = 123670

GCD(298, 830) = ( 298 x 830 ) / 123670

= 298 / 830

= 298

Step2:

LCM(2, 808) = 808

GCD(2, 808) = ( 2 x 808 ) / 808

= 2 / 808

= 2

Step3:

LCM(2, 217) = 434

GCD(2, 217) = ( 2 x 217 ) / 434

= 2 / 217

= 2

So, Greatest Common Divisor of 298, 830, 808, 217 is 1
