What is the prime factorization of the number 63?
Here are the first several prime factors: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29… 63 ÷ 2 = 31.5 – This has a remainder. Let’s try another prime number. 63 ÷ 3 = 21 – No remainder! 3 is one of the factors! 21 ÷ 3 = 7 – No remainder! 3 is one of the factors! 7 ÷ 3 = 2.3333 – There is a remainder. We can’t divide by 3 evenly anymore.
