business and finance debt factoring and invoice discounting# How do you find the no of factors of a number?

Remember that both the

**number**you divide into theoriginal**number**and the result are**factors**. Forexample, since 30/2 = 15, both 2 and 15 are**factors**of 30.Fill these**numbers**into your**factor**list. All thepositive**factors**for 30 are 1, 2, 3, 5, 6, 10, 15,30.

Just so, how do you find the number of factors of a number?

**Basic formula related to factors of a number:**

- Number of factors of N = (a+1)(b+1)(c+1)
- Product of factors of N = N
^{No}^{.}offactors/2. - Sum of factors: ( p
^{0}+p^{1}++p^{a}) (q^{0}+ q^{1}+.+q^{b})(r^{0}+r^{1}++r^{c})/(p^{a}-1)(q^{b}-1)(r^{c}-1)

**find**even

**factors**, just

**find**thetotal

**number**of

**factors**- in this case(4+1)(1+1)(2+1) = 30 total

**factors**- and then subtract the

**number**of

**odd factors**30 total - 6

**odd**= 24even

**factors**.

Regarding this, what is number of factors?

"**Factors**" are the **numbers** you multiply toget another **number**. Some **numbers** have more than onefactorization (more than one way of being factored). For instance,12 can be factored as 1×12, 2×6, or 3×4. A**number** that can only be factored as 1 times itself is called"prime".

No.of **factors**=(1+1)*(2+1)=>6.
