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

Apply this formula for all numbers.

Step1:

LCM(685, 440) = 60280

GCD(685, 440) = ( 685 x 440 ) / 60280

= 685 / 440

= 685

Step2:

LCM(5, 745) = 745

GCD(5, 745) = ( 5 x 745 ) / 745

= 5 / 745

= 5

So, Greatest Common Divisor of 685, 440, 745 is 5
