Given numbers are 345, 391, 104, 623

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 391 are 17 x 23

Prime factors of 104 are 2 x 2 x 2 x 13

Prime factors of 623 are 7 x 89

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

Given numbers are 345, 391, 104, 623

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

Apply this formula for all numbers.

Step1:

LCM(345, 391) = 5865

GCD(345, 391) = ( 345 x 391 ) / 5865

= 345 / 391

= 345

Step2:

LCM(23, 104) = 2392

GCD(23, 104) = ( 23 x 104 ) / 2392

= 23 / 104

= 23

Step3:

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

= 1 / 623

= 1

So, Greatest Common Divisor of 345, 391, 104, 623 is 1
