Given numbers are 408, 422, 279, 991

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

Apply this formula for all numbers.

Step1:

LCM(408, 422) = 86088

GCD(408, 422) = ( 408 x 422 ) / 86088

= 408 / 422

= 408

Step2:

LCM(2, 279) = 558

GCD(2, 279) = ( 2 x 279 ) / 558

= 2 / 279

= 2

Step3:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

So, Greatest Common Divisor of 408, 422, 279, 991 is 1
