Given numbers are 398, 250, 285, 378

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 250 are 2 x 5 x 5 x 5

Prime factors of 285 are 3 x 5 x 19

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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

Given numbers are 398, 250, 285, 378

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

Apply this formula for all numbers.

Step1:

LCM(398, 250) = 49750

GCD(398, 250) = ( 398 x 250 ) / 49750

= 398 / 250

= 398

Step2:

LCM(2, 285) = 570

GCD(2, 285) = ( 2 x 285 ) / 570

= 2 / 285

= 2

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 398, 250, 285, 378 is 1
