All numbers divisible by 22 and 24 are also divisible by which of the following?

221

132

204

250

154

One possible ways of determining the answer from the given is to determine if the number given is divisible by both 22 and 24

A. 221; 221 / 22 = 1.045; 221 / 24 = 9.21

B. 132; 132 / 22 = 6; 132 / 24 = 5.5

C. 204; 204 / 22 = 9.27; 204 / 24 = 8.5

D. 250; 250 / 22 = 11.36; 250/24 = 10.42

E. 154; 154 / 22 = 7; 154 / 24 = 6.416

The answer to the question is letter B.

We may also factor 22 as 2 x 11 and 24 as 2 x 2 x 2 x 3. The factor is, 2 x 11 x 2 x 3 which is equal to 132.
