**How to Find the factors of 151?**

To calculate the factors of any number, here 151 in this case, we have to find all the numbers which will divide 151 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) 151 ÷ 1 = 151
Gives remainder 0 and so are divisible by 151. So please put it on your factor list.
1, ........ 151
```

```
(ii) 151 ÷ 2 = 75.5
Gives remainder 75.5, not being thoroughly divided. So we will not write two on the list.
```

```
(iii) 151 ÷ 3 = 50.33
Gives remainder 50.33, not being thoroughly divided. So we will not write three on the list.
```

```
(iv) 151 ÷ 4 = 37.75
Gives remainder 37.75, not being thoroughly divided. So we will not write four on the list.
```

```
(v) 151 ÷ 5 = 30.2
Gives remainder 30.2, not being thoroughly divided. So we will not write five on the list.
```

```
(vi) Since we don't have any more numbers to calculate, we are putting the numbers so far.
So 1, 151 are factor of 151.
```

**Factors of – 151**

As – 1 and – 151 are negative factors, you get a positive number by multiplying two negatives, like (- 1) × (- 151) = 151.

So, – 1, – 151 are negative factors of 151.

**All factors of 151**

Here is a list of all the positive and negative factors of 151 in numerical order.

Positive Factors of 151 = 1, 151

Negative Factors of 151 = – 1, – 151

So, – 1, – 151, 1, 151 All factors of 151.

**Factors of 151 in pairs**

1 and 151 are a factor pair of 151 since 1 x 151 = 151

Therefore, the pair factors of 151 are (1, 151).

**Negative pair factors of 151**

(-1) × (-151) = (-1, -151)

Therefore, the Negative pair factors are (-1, -151).
