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

Apply this formula for all numbers.

Step1:

LCM(777, 297) = 76923

GCD(777, 297) = ( 777 x 297 ) / 76923

= 777 / 297

= 777

Step2:

LCM(3, 78) = 78

GCD(3, 78) = ( 3 x 78 ) / 78

= 3 / 78

= 3

So, Greatest Common Divisor of 777, 297, 78 is 3
