Given numbers are 308, 221, 423, 187

The list of prime factors of all numbers are

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 221 are 13 x 17

Prime factors of 423 are 3 x 3 x 47

Prime factors of 187 are 11 x 17

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

Given numbers are 308, 221, 423, 187

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

Apply this formula for all numbers.

Step1:

LCM(308, 221) = 68068

GCD(308, 221) = ( 308 x 221 ) / 68068

= 308 / 221

= 308

Step2:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

Step3:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

So, Greatest Common Divisor of 308, 221, 423, 187 is 1
