Given numbers are 408, 643, 349

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

Apply this formula for all numbers.

Step1:

LCM(408, 643) = 262344

GCD(408, 643) = ( 408 x 643 ) / 262344

= 408 / 643

= 408

Step2:

LCM(1, 349) = 349

GCD(1, 349) = ( 1 x 349 ) / 349

= 1 / 349

= 1

So, Greatest Common Divisor of 408, 643, 349 is 1
