Factors of Numbers from 21 to 30

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. 21Factors$1,$ $3,$ $7$ and $21$ are factors of $21$.
2. 22Factors$1,$ $2,$ $11,$ and $22$ are factors of $22$.
3. 23Factors$1$ and $23$ are factors of $23$.
4. 24Factors$1,$ $2,$ $3,$ $4,$ $6,$ $8,$ $12$ and $24$ are factors of $24$.
5. 25Factors$1,$ $5$ and $25$ are factors of $25$.
6. 26Factors$1,$ $2,$ $13$ and $26$ are factors of $26$.
7. 27Factors$1,$ $3,$ $9$ and $27$ are factors of $27$.
8. 28Factors$1,$ $2,$ $4,$ $7,$ $14$ and $28$ are factors of $28$.
9. 29Factors$1$ and $29$ are factors of $29$.
10. 30Factors$1,$ $2,$ $3,$ $5,$ $6,$ $10,$ $15$ and $30$ are factors of $30$.
