Given numbers are 280, 426, 398, 235

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 426 are 2 x 3 x 71

Prime factors of 398 are 2 x 199

Prime factors of 235 are 5 x 47

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

Given numbers are 280, 426, 398, 235

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

Apply this formula for all numbers.

Step1:

LCM(280, 426) = 59640

GCD(280, 426) = ( 280 x 426 ) / 59640

= 280 / 426

= 280

Step2:

LCM(2, 398) = 398

GCD(2, 398) = ( 2 x 398 ) / 398

= 2 / 398

= 2

Step3:

LCM(2, 235) = 470

GCD(2, 235) = ( 2 x 235 ) / 470

= 2 / 235

= 2

So, Greatest Common Divisor of 280, 426, 398, 235 is 1
