That is, every term of σ(mn) (the sum of all divisors of mn) occurs exactly once in the sum σ(m)σ(n) (the product of all divisors of m and n). The converse is also true: every such product is a divisor of mn, so the sums must be the same. flag for brick enclosed mailbox

WebbThe prime factorization of a number can be found using a factor tree . Start by finding two factors which, multiplied together, give the number. Keep splitting each branch of the tree into a pair of factors until all the branches terminate in prime numbers. Here is a factor tree for 1386 . We start by noticing that 1386 is even, so 2 is a factor. WebbTo save writing, I'll make the convention that when I write "", I mean to sum over all the positive divisors of a positive integer n. Thus, the divisor sum of f evaluated at a positive integer n takes the positive divisors of n, plugs them into f, and adds up the results. A similar convention will hold for products.
