Given numbers are 345, 803, 406, 289

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 803 are 11 x 73

Prime factors of 406 are 2 x 7 x 29

Prime factors of 289 are 17 x 17

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

Given numbers are 345, 803, 406, 289

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

Apply this formula for all numbers.

Step1:

LCM(345, 803) = 277035

GCD(345, 803) = ( 345 x 803 ) / 277035

= 345 / 803

= 345

Step2:

LCM(1, 406) = 406

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

= 1 / 406

= 1

Step3:

LCM(1, 289) = 289

GCD(1, 289) = ( 1 x 289 ) / 289

= 1 / 289

= 1

So, Greatest Common Divisor of 345, 803, 406, 289 is 1
