Given numbers are 418, 308, 170, 406

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

Apply this formula for all numbers.

Step1:

LCM(418, 308) = 5852

GCD(418, 308) = ( 418 x 308 ) / 5852

= 418 / 308

= 418

Step2:

LCM(22, 170) = 1870

GCD(22, 170) = ( 22 x 170 ) / 1870

= 22 / 170

= 22

Step3:

LCM(2, 406) = 406

GCD(2, 406) = ( 2 x 406 ) / 406

= 2 / 406

= 2

So, Greatest Common Divisor of 418, 308, 170, 406 is 2
