Given numbers are 685, 135, 404

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

Apply this formula for all numbers.

Step1:

LCM(685, 135) = 18495

GCD(685, 135) = ( 685 x 135 ) / 18495

= 685 / 135

= 685

Step2:

LCM(5, 404) = 2020

GCD(5, 404) = ( 5 x 404 ) / 2020

= 5 / 404

= 5

So, Greatest Common Divisor of 685, 135, 404 is 1
