Given numbers are 980, 686, 340, 818

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

Apply this formula for all numbers.

Step1:

LCM(980, 686) = 6860

GCD(980, 686) = ( 980 x 686 ) / 6860

= 980 / 686

= 980

Step2:

LCM(98, 340) = 16660

GCD(98, 340) = ( 98 x 340 ) / 16660

= 98 / 340

= 98

Step3:

LCM(2, 818) = 818

GCD(2, 818) = ( 2 x 818 ) / 818

= 2 / 818

= 2

So, Greatest Common Divisor of 980, 686, 340, 818 is 2
