Given numbers are 231, 808, 221, 159

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

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

Prime factors of 221 are 13 x 17

Prime factors of 159 are 3 x 53

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

Given numbers are 231, 808, 221, 159

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

Apply this formula for all numbers.

Step1:

LCM(231, 808) = 186648

GCD(231, 808) = ( 231 x 808 ) / 186648

= 231 / 808

= 231

Step2:

LCM(1, 221) = 221

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

= 1 / 221

= 1

Step3:

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

= 1 / 159

= 1

So, Greatest Common Divisor of 231, 808, 221, 159 is 1
