Question

Find the smallest four digit number which Is divisible by 18 24 and 32

Answer 1

Use the ladder method. First list all the numbers. Since 2 is a common factor among all the numbers, it can be factored out, and the 3 numbers can be simplified to 9,12, and 16. Since there are no more common factors, we multiply all 4 numbers to get 3456.

Answer 2

Answer:

The smallest four digit number divisible by 18, 24, and 32 is 1152.

Step-by-step explanation:

The LCM of the 3 numbers are 288

Then, the smallest four-digit number would equal 1152 (288*4)

Take L.C.M. of 18,24,32= 288

Resulting in 1152 :)
