Given numbers are 646, 385, 473

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

Apply this formula for all numbers.

Step1:

LCM(646, 385) = 248710

GCD(646, 385) = ( 646 x 385 ) / 248710

= 646 / 385

= 646

Step2:

LCM(1, 473) = 473

GCD(1, 473) = ( 1 x 473 ) / 473

= 1 / 473

= 1

So, Greatest Common Divisor of 646, 385, 473 is 1
