The number 7 is a factor of 1001.
explain how you know 1001 is a multiple of 7?
How does knowing that 7 is a factor of 1001 help you to get another factor of 1001?

    since 7 is a factor that means it divides 1001 evenly. That means that there is another number k such that 7k = 1001

    so, 1001 is a multiple of 7: 1001 = 7k
    for some integer k.

    to find k, divide 1001/7: 143 is another factor
