Factors of Numbers from 11 to 20

The numbers $1, 2, 3, 4, 5, 6, 7, 8, 9$ and $10$ are the natural numbers, and the numbers from $1$ to $10$ can be expressed as a product of two or more natural numbers. So, let’s learn how to find the factors of the numbers from one to ten with proof.

1. 11Factors$1$ is a factor of itself.
2. 12Factors$1$ and $2$ are factors of $2$.
3. 13Factors$1$ and $3$ are factors of $3$.
4. 14Factors$1,$ $2$ and $4$ are factors of $4$.
5. 15Factors$1$ and $5$ are factors of $5$.
6. 16Factors$1,$ $2,$ $3$ and $6$ are factors of $6$.
7. 17Factors$1$ and $7$ are factors of $7$.
8. 18Factors$1,$ $2,$ $4$ and $8$ are factors of $8$.
9. 19Factors$1,$ $3$ and $9$ are factors of $9$.
10. 20Factors$1,$ $2,$ $5$ and $10$ are factors of $10$.
