Both 7 and 13 are factors of 1001. Explain how to use this information to get two other factors.
alexdok [17]

Answer:

Step-by-step explanation:

"Factors" are the numbers you multiply to get another number. For instance, factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (more than one way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4.
