Given numbers are 340, 161, 409

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

Apply this formula for all numbers.

Step1:

LCM(340, 161) = 54740

GCD(340, 161) = ( 340 x 161 ) / 54740

= 340 / 161

= 340

Step2:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

So, Greatest Common Divisor of 340, 161, 409 is 1
