9. Find the smallest 4-digit number which is divisible by 18, 24 and 32.
​

Answer 1

Answer:

1152

Step By Step Explanation:

LCM of 18, 24 and 32:

2 | 18  24 32

2 |   9  12  16

2 |   9   6    8

3 |   9   3    4

      3    1     4

LCM = 2 x 2 x 2  x 3 x 3 × 4 = 288

Now, 288 × 1 = 288

         288 × 2 = 576

         288 × 3 = 864

         288 × 4 =  1152

The smallest 4-digit number which is divisible by 18, 24 and 32 = 288 × 4

                                                                                                              = 1152
