Given numbers are 784, 223, 285

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

Apply this formula for all numbers.

Step1:

LCM(784, 223) = 174832

GCD(784, 223) = ( 784 x 223 ) / 174832

= 784 / 223

= 784

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

So, Greatest Common Divisor of 784, 223, 285 is 1
