Given numbers are 398, 303, 683, 980

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

Apply this formula for all numbers.

Step1:

LCM(398, 303) = 120594

GCD(398, 303) = ( 398 x 303 ) / 120594

= 398 / 303

= 398

Step2:

LCM(1, 683) = 683

GCD(1, 683) = ( 1 x 683 ) / 683

= 1 / 683

= 1

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 398, 303, 683, 980 is 1
