Given numbers are 775, 680, 305

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

Apply this formula for all numbers.

Step1:

LCM(775, 680) = 105400

GCD(775, 680) = ( 775 x 680 ) / 105400

= 775 / 680

= 775

Step2:

LCM(5, 305) = 305

GCD(5, 305) = ( 5 x 305 ) / 305

= 5 / 305

= 5

So, Greatest Common Divisor of 775, 680, 305 is 5
