Given numbers are 209, 395, 288, 406

The list of prime factors of all numbers are

Prime factors of 209 are 11 x 19

Prime factors of 395 are 5 x 79

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 209, 395, 288, 406

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

Apply this formula for all numbers.

Step1:

LCM(209, 395) = 82555

GCD(209, 395) = ( 209 x 395 ) / 82555

= 209 / 395

= 209

Step2:

LCM(1, 288) = 288

GCD(1, 288) = ( 1 x 288 ) / 288

= 1 / 288

= 1

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 209, 395, 288, 406 is 1
