Given numbers are 980, 320, 388, 802

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

Apply this formula for all numbers.

Step1:

LCM(980, 320) = 15680

GCD(980, 320) = ( 980 x 320 ) / 15680

= 980 / 320

= 980

Step2:

LCM(20, 388) = 1940

GCD(20, 388) = ( 20 x 388 ) / 1940

= 20 / 388

= 20

Step3:

LCM(4, 802) = 1604

GCD(4, 802) = ( 4 x 802 ) / 1604

= 4 / 802

= 4

So, Greatest Common Divisor of 980, 320, 388, 802 is 2
