Given numbers are 386, 685, 881, 405

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

Apply this formula for all numbers.

Step1:

LCM(386, 685) = 264410

GCD(386, 685) = ( 386 x 685 ) / 264410

= 386 / 685

= 386

Step2:

LCM(1, 881) = 881

GCD(1, 881) = ( 1 x 881 ) / 881

= 1 / 881

= 1

Step3:

LCM(1, 405) = 405

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

= 1 / 405

= 1

So, Greatest Common Divisor of 386, 685, 881, 405 is 1
