Given numbers are 422, 406, 788, 393

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

Apply this formula for all numbers.

Step1:

LCM(422, 406) = 85666

GCD(422, 406) = ( 422 x 406 ) / 85666

= 422 / 406

= 422

Step2:

LCM(2, 788) = 788

GCD(2, 788) = ( 2 x 788 ) / 788

= 2 / 788

= 2

Step3:

LCM(2, 393) = 786

GCD(2, 393) = ( 2 x 393 ) / 786

= 2 / 393

= 2

So, Greatest Common Divisor of 422, 406, 788, 393 is 1
