Given numbers are 408, 279, 406, 829

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

Apply this formula for all numbers.

Step1:

LCM(408, 279) = 37944

GCD(408, 279) = ( 408 x 279 ) / 37944

= 408 / 279

= 408

Step2:

LCM(3, 406) = 1218

GCD(3, 406) = ( 3 x 406 ) / 1218

= 3 / 406

= 3

Step3:

LCM(1, 829) = 829

GCD(1, 829) = ( 1 x 829 ) / 829

= 1 / 829

= 1

So, Greatest Common Divisor of 408, 279, 406, 829 is 1
