Given numbers are 406, 671, 856

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

Apply this formula for all numbers.

Step1:

LCM(406, 671) = 272426

GCD(406, 671) = ( 406 x 671 ) / 272426

= 406 / 671

= 406

Step2:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

So, Greatest Common Divisor of 406, 671, 856 is 1
