Given numbers are 166, 470, 18, 454

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

Apply this formula for all numbers.

Step1:

LCM(166, 470) = 39010

GCD(166, 470) = ( 166 x 470 ) / 39010

= 166 / 470

= 166

Step2:

LCM(2, 18) = 18

GCD(2, 18) = ( 2 x 18 ) / 18

= 2 / 18

= 2

Step3:

LCM(2, 454) = 454

GCD(2, 454) = ( 2 x 454 ) / 454

= 2 / 454

= 2

So, Greatest Common Divisor of 166, 470, 18, 454 is 2
