Given numbers are 815, 497, 728

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

Apply this formula for all numbers.

Step1:

LCM(815, 497) = 405055

GCD(815, 497) = ( 815 x 497 ) / 405055

= 815 / 497

= 815

Step2:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

So, Greatest Common Divisor of 815, 497, 728 is 1
