Factors of Numbers from 71 to 80

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. 71Factors$1$ and $71$ are factors of $71$.
2. 72Factors$1,$ $2,$ $3,$ $4,$ $6,$ $8,$ $9,$ $12,$ $18,$ $24,$ $36$ and $72$ are factors of $72$.
3. 73Factors$1$ and $73$ are factors of $73$.
4. 74Factors$1,$ $2,$ $37$ and $74$ are factors of $74$.
5. 75Factors$1,$ $3,$ $5,$ $15,$ $25$ and $75$ are factors of $75$.
6. 76Factors$1,$ $2,$ $4,$ $19,$ $38$ and $76$ are factors of $76$.
7. 77Factors$1,$ $7,$ $11$ and $77$ are factors of $77$.
8. 78Factors$1,$ $2,$ $3,$ $6,$ $13,$ $26,$ $39$ and $78$ are factors of $78$.
9. 79Factors$1$ and $79$ are factors of $79$.
10. 80Factors$1,$ $2,$ $4,$ $5,$ $8,$ $10,$ $16,$ $20,$ $40$ and $80$ are factors of $80$.
