Given numbers are 980, 688, 430, 430

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

Apply this formula for all numbers.

Step1:

LCM(980, 688) = 168560

GCD(980, 688) = ( 980 x 688 ) / 168560

= 980 / 688

= 980

Step2:

LCM(4, 430) = 860

GCD(4, 430) = ( 4 x 430 ) / 860

= 4 / 430

= 4

Step3:

LCM(2, 430) = 430

GCD(2, 430) = ( 2 x 430 ) / 430

= 2 / 430

= 2

So, Greatest Common Divisor of 980, 688, 430, 430 is 2
