Given numbers are 789, 688, 513

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

Apply this formula for all numbers.

Step1:

LCM(789, 688) = 542832

GCD(789, 688) = ( 789 x 688 ) / 542832

= 789 / 688

= 789

Step2:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

So, Greatest Common Divisor of 789, 688, 513 is 1
