Given numbers are 678, 464, 195, 399

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 464 are 2 x 2 x 2 x 2 x 29

Prime factors of 195 are 3 x 5 x 13

Prime factors of 399 are 3 x 7 x 19

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

Given numbers are 678, 464, 195, 399

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

Apply this formula for all numbers.

Step1:

LCM(678, 464) = 157296

GCD(678, 464) = ( 678 x 464 ) / 157296

= 678 / 464

= 678

Step2:

LCM(2, 195) = 390

GCD(2, 195) = ( 2 x 195 ) / 390

= 2 / 195

= 2

Step3:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

So, Greatest Common Divisor of 678, 464, 195, 399 is 1
