4900 is divisible by 1, 2, 4, 5, 7, 10, 20, 25, 35, 49, 50, 100, 175, 245, 350, 700, 1225, 2450, 4900.
Nothing can go evenly into 21 or 17. They are both odd numbers and therefore cannot be evenly divided.
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)
