Given numbers are 406, 344, 149, 217

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

Apply this formula for all numbers.

Step1:

LCM(406, 344) = 69832

GCD(406, 344) = ( 406 x 344 ) / 69832

= 406 / 344

= 406

Step2:

LCM(2, 149) = 298

GCD(2, 149) = ( 2 x 149 ) / 298

= 2 / 149

= 2

Step3:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

So, Greatest Common Divisor of 406, 344, 149, 217 is 1
