Factors of Numbers from 61 to 70

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. 61Factors$1$ and $61$ are factors of $61$.
2. 62Factors$1,$ $2,$ $31$ and $62$ are factors of $62$.
3. 63Factors$1,$ $3,$ $7,$ $9,$ $21$ and $63$ are factors of $63$.
4. 64Factors$1,$ $2,$ $4,$ $8,$ $16,$ $32$ and $64$ are factors of $64$.
5. 65Factors$1,$ $5,$ $13$ and $65$ are factors of $65$.
6. 66Factors$1,$ $2,$ $3,$ $6,$ $11,$ $22,$ $33$ and $66$ are factors of $66$.
7. 67Factors$1$ and $67$ are factors of $67$.
8. 68Factors$1,$ $2,$ $4,$ $17,$ $34$ and $68$ are factors of $68$.
9. 69Factors$1,$ $3,$ $23$ and $69$ are factors of $69$.
10. 70Factors$1,$ $2,$ $5,$ $7,$ $10,$ $14,$ $35$ and $70$ are factors of $70$.
