Given numbers are 678, 430, 38, 447

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 430 are 2 x 5 x 43

Prime factors of 38 are 2 x 19

Prime factors of 447 are 3 x 149

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

Given numbers are 678, 430, 38, 447

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

Apply this formula for all numbers.

Step1:

LCM(678, 430) = 145770

GCD(678, 430) = ( 678 x 430 ) / 145770

= 678 / 430

= 678

Step2:

LCM(2, 38) = 38

GCD(2, 38) = ( 2 x 38 ) / 38

= 2 / 38

= 2

Step3:

LCM(2, 447) = 894

GCD(2, 447) = ( 2 x 447 ) / 894

= 2 / 447

= 2

So, Greatest Common Divisor of 678, 430, 38, 447 is 1
