The meaning of a factor is a whole number that can divide a greater number evenly. Some numbers known as highly composite numbers can have very large numbers of factors. We just add up all the factors of each prime separately and multiply the results together so the factors of 12 sum to 12413 7times 4 28.

Let n be non-prime. The numbers 72 8 24 10 5 45 36 15 are grouped in pairs so that each pair has the same product. The goal of prime factorization is to keep breaking a number down until there are only primes left.
