Given numbers are 777, 798, 515, 863

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

Apply this formula for all numbers.

Step1:

LCM(777, 798) = 29526

GCD(777, 798) = ( 777 x 798 ) / 29526

= 777 / 798

= 777

Step2:

LCM(21, 515) = 10815

GCD(21, 515) = ( 21 x 515 ) / 10815

= 21 / 515

= 21

Step3:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

So, Greatest Common Divisor of 777, 798, 515, 863 is 1
