Given numbers are 788, 789, 813

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

Apply this formula for all numbers.

Step1:

LCM(788, 789) = 621732

GCD(788, 789) = ( 788 x 789 ) / 621732

= 788 / 789

= 788

Step2:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 788, 789, 813 is 1
