A composite number is any number who has more than 2 factors. ex: 10 Factors of 10 = 1, 2, 5, 10. 10 has 4 factors, and is composite. ex: 7 Factors of 7 = 1, 7. 7 has 2 factors, and is not composite. Anything with 2 factors is called Prime. it has factors of 1 and itself only. To find the factors of 208, see if you can divide it by a number evenly. 2 will work, since 208 is even. This means, so far the factors are 1, 2 and 208. (there are more) But I will stop here, because 208 has at least 3 factors. 3 is more than 2, and when a number has more than 2 factors.... 208 is composite.
