Given numbers are 813, 559, 455

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

Apply this formula for all numbers.

Step1:

LCM(813, 559) = 454467

GCD(813, 559) = ( 813 x 559 ) / 454467

= 813 / 559

= 813

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 813, 559, 455 is 1
