Given numbers are 775, 630, 395, 255

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

Apply this formula for all numbers.

Step1:

LCM(775, 630) = 97650

GCD(775, 630) = ( 775 x 630 ) / 97650

= 775 / 630

= 775

Step2:

LCM(5, 395) = 395

GCD(5, 395) = ( 5 x 395 ) / 395

= 5 / 395

= 5

Step3:

LCM(5, 255) = 255

GCD(5, 255) = ( 5 x 255 ) / 255

= 5 / 255

= 5

So, Greatest Common Divisor of 775, 630, 395, 255 is 5
