Given numbers are 422, 657, 439, 405

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

Apply this formula for all numbers.

Step1:

LCM(422, 657) = 277254

GCD(422, 657) = ( 422 x 657 ) / 277254

= 422 / 657

= 422

Step2:

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

= 1 / 439

= 1

Step3:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

So, Greatest Common Divisor of 422, 657, 439, 405 is 1
