**40**.

**How many Factors of 40**? When we counted the

**Factors of 40**that we listed above, we found that

**40**has 8

**Positive Factors**and 8 Negative

**Factors**. Thus, the total number of

**Factors of 40**is 16.

Likewise, people ask, what are all of the factors of 40?

**40** = 1 x **40**, 2 x 20, 4 x 10, or 5 x 8. **Factors of 40**: 1, 2, 4, 5, 8, 10, 20, **40**. Prime factorization: **40** = 2 x 2 x 2 x 5, which can also be written 2³ x 5.

what is a factor of 40 larger than 5? **Greatest Common Factor (GCF**) of two numbers the factors of 40 are 1, 2, 4, 5, 8, 10, 20 and 40, and the factors of 50 are 1, 2, 5, 10, 25 and 50.

One may also ask, how many positive factors are there?

To determine the total number of **positive factors**, we first break 441 into its prime **factors**, add 1 to each exponent and multiply the results. So the number of **factors** is (2 + 1)(2 + 1) = 3 x 3 = 9.

Which number is not a factor of 40?

-- 6 is **not a factor of 40**. [**40** is **not** divisible by 7.] The next **number**, 8 , already appears on the list above (on the right). For **numbers** greater than 8 to be **factors of 40** they would have to be multiplied by something less than the 5 we use in 8×5=**40** .
