Given numbers are 404, 689, 665

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

Apply this formula for all numbers.

Step1:

LCM(404, 689) = 278356

GCD(404, 689) = ( 404 x 689 ) / 278356

= 404 / 689

= 404

Step2:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 404, 689, 665 is 1
