# What Is the Smallest Number That Can Be Divided by Every Number from 1 to 10?

If you are a math genius, or even someone who paid attention in high school algebra, you probably figured that out quite easily. And if not, we'll tell you -- the smallest number that can be divided by every number from 1 to 10 is 2,520. Read on for the solution.

It's all about finding the unique factors among the numbers 1-10, which are 9, 8, 7, and 5. All numbers are divisible by 1, so we can ignore that. And 2, 3, 4, 6, and 10 are made up of the same factors that make up 9, 8, 7, and 5. For example, any number divisible by 9 is also divisible by 3, while any number divisible by 8 is also divisible by 2 and 4. So the final calculation is simply 9 x 8 x 7 x 5 = 2,520.
