Given numbers are 628, 655, 815

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

Apply this formula for all numbers.

Step1:

LCM(628, 655) = 411340

GCD(628, 655) = ( 628 x 655 ) / 411340

= 628 / 655

= 628

Step2:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 628, 655, 815 is 1
