Given numbers are 398, 706, 631, 499

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

Apply this formula for all numbers.

Step1:

LCM(398, 706) = 140494

GCD(398, 706) = ( 398 x 706 ) / 140494

= 398 / 706

= 398

Step2:

LCM(2, 631) = 1262

GCD(2, 631) = ( 2 x 631 ) / 1262

= 2 / 631

= 2

Step3:

LCM(1, 499) = 499

GCD(1, 499) = ( 1 x 499 ) / 499

= 1 / 499

= 1

So, Greatest Common Divisor of 398, 706, 631, 499 is 1
