What are the factors of 19?

The factors of 19 are numbers that can divide 19 completely, leaving the rest 0. The number 19 is also known as the factors of 19. Because 19 is a prime number, there are only two factors, such as 1 or the number itself. The factors of 19, therefore, are 1 and 19.

How to Calculate the factors of 19?

The method of calculating the factors of 19 is as follows. First, every number is divisible by itself and 1.
Therefore, the factors of 19 are 1, …
We can find all factors of a number by dividing it by 1, 2, 3, 4…

(i) 19 ÷ 1 = 19

This division gives the remainder 0 and so is divisible by 19. So please put them 1 and 19 in your factor list.

1, …….. 19

(ii) 19 ÷ 2 = 9.5

This division gives the remainder 9.5, needing to be more thoroughly divided. So we will not write 2 and 9.5 on the list.

(iii) 19 ÷ 3 = 6.33

This division gives the remainder 6.33, needing to be more thoroughly divided. So we will not write 3 and 6.33 on the list.

(iv) 19 ÷ 4 = 4.75

This division gives the remainder 4.75, needing to be more thoroughly divided. So we will not write 4 and 4.75 on the list.

(v) 19 ÷ 5 = 3.8

This division gives the remainder 3.8, not being thoroughly divided. So we will not write 5 and 3.8 on the list.

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

So 1, 19 are a factor of 19.

Factors of -19

As – 1 and – 19 are negative factors, you get a positive number by multiplying two negatives, like (- 1) × (- 19) = 19.

So – 1, – 19 are a negative factors of 19.

All factors of 19

Here is a list of all the positive and negative factors of 19 in numerical order.

Positive Factors of 19 = 1, 19
Negative Factors of 19 = – 1, – 19

Factors of 19 in pairs

1 and 19 are a factor pair of 19 since 1 x 19 = 19

Therefore, the pair factors of 19 are (1, 19).
