How many factors has 16?

So 1, 2, 4, and 8 are factors of 16. Students only need to try the numbers up to half the number for which they are finding the factors. Numbers greater than half will not divide evenly.

Do all numbers have an even number of factors?

A factor is a number that divides into another number exactly and without leaving a remainder. Most numbers have an even number of factors; however, a square number has an odd number of factors. A prime number has only two factors – the number itself and 1.

Can 2 be a factor of an odd number?

Here is the logic behind the multiplication rules: an even number is divisible by 2, so that means it has 2 as a factor. … An odd number is like a bunch of pairs with one left over. So if you add two odd numbers, you have a bunch of pairs and the two lonely units make a final pair, and the sum of two odd numbers is even.
