Given numbers are 814, 256, 405, 173

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

Apply this formula for all numbers.

Step1:

LCM(814, 256) = 104192

GCD(814, 256) = ( 814 x 256 ) / 104192

= 814 / 256

= 814

Step2:

LCM(2, 405) = 810

GCD(2, 405) = ( 2 x 405 ) / 810

= 2 / 405

= 2

Step3:

LCM(1, 173) = 173

GCD(1, 173) = ( 1 x 173 ) / 173

= 1 / 173

= 1

So, Greatest Common Divisor of 814, 256, 405, 173 is 1
