Given numbers are 856, 548, 129, 406

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

Apply this formula for all numbers.

Step1:

LCM(856, 548) = 117272

GCD(856, 548) = ( 856 x 548 ) / 117272

= 856 / 548

= 856

Step2:

LCM(4, 129) = 516

GCD(4, 129) = ( 4 x 129 ) / 516

= 4 / 129

= 4

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 856, 548, 129, 406 is 1
