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

Apply this formula for all numbers.

Step1:

LCM(777, 903) = 33411

GCD(777, 903) = ( 777 x 903 ) / 33411

= 777 / 903

= 777

Step2:

LCM(21, 720) = 5040

GCD(21, 720) = ( 21 x 720 ) / 5040

= 21 / 720

= 21

Step3:

LCM(3, 915) = 915

GCD(3, 915) = ( 3 x 915 ) / 915

= 3 / 915

= 3

So, Greatest Common Divisor of 777, 903, 720, 915 is 3
