Composite numbers.
All of them can be divided by 2, but not necessarily evenly. Only the even numbers from 2 to 798 can be evenly divided by two. There are 399 of those.
All of these numbers are composite except for 2, which is prime.Prime numbers are numbers that can only be divided evenly by 1 and itself.Composite numbers can be divided evenly by 1, itself, and at least one more number.
use the divisibility rules. because these are all multiples of 10 right off the bat, you can divide all of them by 10 and use the numbers 5, 10 and 490 as your numbers instead. you can then use factor trees and prime factorization to help you. (I assumed that "divided evenly" you actually meant "multiplied evenly" as a smaller number cannot be divided evenly by a larger number)
It can not be divided by anything and come out as an evenly. only numbers for example like 0 6 15 21 and 18 if they were divided by three would be able to ccome out evenly.
