Mathematics

In mathematics, the number eight is an even number. This means you can divide it by two without any remainder. Eight is also a composite number. This means it has more than two factors (numbers that divide into it evenly). Its factors are 1, 2, 4, and 8.

Eight as a Power of Two

Eight is special because it is a power of two. This means you can get eight by multiplying the number two by itself a certain number of times. For eight, you multiply 2 by itself three times: 2 × 2 × 2 = 8. This is also written as 2³.
