Given numbers are 399, 191, 222, 280

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 191 are 191

Prime factors of 222 are 2 x 3 x 37

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 399, 191, 222, 280

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

Apply this formula for all numbers.

Step1:

LCM(399, 191) = 76209

GCD(399, 191) = ( 399 x 191 ) / 76209

= 399 / 191

= 399

Step2:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 399, 191, 222, 280 is 1
