Given numbers are 404, 257, 609

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

Apply this formula for all numbers.

Step1:

LCM(404, 257) = 103828

GCD(404, 257) = ( 404 x 257 ) / 103828

= 404 / 257

= 404

Step2:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

So, Greatest Common Divisor of 404, 257, 609 is 1
