Given numbers are 689, 663, 982, 789

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

Apply this formula for all numbers.

Step1:

LCM(689, 663) = 35139

GCD(689, 663) = ( 689 x 663 ) / 35139

= 689 / 663

= 689

Step2:

LCM(13, 982) = 12766

GCD(13, 982) = ( 13 x 982 ) / 12766

= 13 / 982

= 13

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 689, 663, 982, 789 is 1
