What is the smallest number perfectly divisible by numbers 1-8?

Answer 1

9

Answer 2

I could write down the answer, but it will be much more fun for you to do it yourself. Write down the prime factors of each number:

2 = 2

3 = 3

4 = 22

etc.

Then, for each individual Prime number, take the highest power (in this case, the only prime number with a power higher than 1 is 23), and multiply everything together.
