Given numbers are 394, 930, 405, 388

The list of prime factors of all numbers are

Prime factors of 394 are 2 x 197

Prime factors of 930 are 2 x 3 x 5 x 31

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 388 are 2 x 2 x 97

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

Given numbers are 394, 930, 405, 388

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

Apply this formula for all numbers.

Step1:

LCM(394, 930) = 183210

GCD(394, 930) = ( 394 x 930 ) / 183210

= 394 / 930

= 394

Step2:

LCM(2, 405) = 810

GCD(2, 405) = ( 2 x 405 ) / 810

= 2 / 405

= 2

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 394, 930, 405, 388 is 1
