Given numbers are 455, 713, 815

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

Apply this formula for all numbers.

Step1:

LCM(455, 713) = 324415

GCD(455, 713) = ( 455 x 713 ) / 324415

= 455 / 713

= 455

Step2:

LCM(1, 815) = 815

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

= 1 / 815

= 1

So, Greatest Common Divisor of 455, 713, 815 is 1
