Given numbers are 806, 682, 989, 440

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

Apply this formula for all numbers.

Step1:

LCM(806, 682) = 8866

GCD(806, 682) = ( 806 x 682 ) / 8866

= 806 / 682

= 806

Step2:

LCM(62, 989) = 61318

GCD(62, 989) = ( 62 x 989 ) / 61318

= 62 / 989

= 62

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 806, 682, 989, 440 is 1
