**How to Find the factors of 181?**

To calculate the factors of any number, here 181 in this case, we have to find all the numbers which will divide 181 without leaving any remainder. We start with the number 1, then go on checking the numbers 2, 3, 4, 5, 6, 7, etc. The number 1 and the number itself are always factors of the given number.

(i) 181 ÷ 1 = 181

Gives remainder 0 and so are divisible by 181. So please put it on your factor list.

1 | … | 181 |

(ii) Since we don’t have any more numbers to calculate, we are putting the numbers so far.

So 1, 181 are factor of 181.

**Factors of – 181**

As – 1 and – 181 are negative factors, you get a positive number by multiplying two negatives, like (- 1) × (- 181) = 181.

So, – 1, – 181 are negative factor of 181.

**All factors of 181**

Here is a list of all the positive and negative factors of 181 in numerical order.

Positive Factors of 181 = 1, 181

Negative Factors of 181 = – 1, – 181

So, – 1, – 181, 1, 181 All factors of 181.

**Factors of 181 in pairs**

1 and 181 are a factor pair of 181 since 1 x 181 = 181

Therefore, the pair factors of 181 are (1, 181).

**Negative pair factors of 181**

(-1) × (-181) = (-1, -181)

Therefore, the Negative pair factors are (-1, -181).
