Given numbers are 394, 607, 840, 345

The list of prime factors of all numbers are

Prime factors of 394 are 2 x 197

Prime factors of 607 are 607

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 345 are 3 x 5 x 23

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

Given numbers are 394, 607, 840, 345

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

Apply this formula for all numbers.

Step1:

LCM(394, 607) = 239158

GCD(394, 607) = ( 394 x 607 ) / 239158

= 394 / 607

= 394

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

So, Greatest Common Divisor of 394, 607, 840, 345 is 1
