Given numbers are 406, 616, 80, 438

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

Apply this formula for all numbers.

Step1:

LCM(406, 616) = 17864

GCD(406, 616) = ( 406 x 616 ) / 17864

= 406 / 616

= 406

Step2:

LCM(14, 80) = 560

GCD(14, 80) = ( 14 x 80 ) / 560

= 14 / 80

= 14

Step3:

LCM(2, 438) = 438

GCD(2, 438) = ( 2 x 438 ) / 438

= 2 / 438

= 2

So, Greatest Common Divisor of 406, 616, 80, 438 is 2
