The factors of 9 are 1, 3, and 9 i.e. F9 = {1, 3, 9}. The factors of 9 are those numbers that can divide 9 without leaving a remainder.
We can check if these
numbers are factors of 9 by dividing 9 by each of them. If the result is a
whole number, then the number is a factor of 9. Let's do this for each of the
numbers listed above:
·
1 is a factor of 9
because 9 divided by 1 is 9.
·
3 is a factor of 9
because 9 divided by 3 is 3.
·
9 is a factor of 9
because 9 divided by 9 is 1.
How to Find Factors of 9?
1 and the number
itself are the factors of every number. So, 1 and 9 are two factors of 9. To
find the other factors of 9, we can start by dividing 9 by the numbers between
1 and 9. If we divide 9 by 2, we get a remainder of 1. Therefore, 2 is not a
factor of 9. If we divide 9 by 3, we get a remainder of 0. Therefore, 3 is a
factor of 9.
Next, we can check if
4 is a factor of 9. If we divide 9 by 4, we get a remainder of 1. Therefore, 4
is not a factor of 9. We can continue this process for all the possible factors
of 9.
Through this process,
we can find that the factors of 9 are 1, 3, and 9. These are the only numbers
that can divide 9 without leaving a remainder.

Properties of the Factors of 9
The factors of 9 have
some interesting properties. One of the properties is that the sum of the
factors of 9 is equal to 13. We can see this by adding all the factors of 9
together:
1 + 3 + 9 = 13
Another property of the
factors of 9 is that they are all odd numbers. This is because 9 is an odd
number, and any even number cannot divide an odd number without leaving a
remainder.
Another property of
the factors of 9 is that the only factor of 9 except 1 and 9 that is 3 is a
prime number.
Applications of the Factors of 9
The factors of 9 have
several applications in mathematics. One of the applications is in finding the
highest common factor (HCF) of two or more numbers. The HCF is the largest
factor that two or more numbers have in common. For example, to find the HCF of
9 and 15, we need to find the factors of both numbers and identify the largest
factor they have in common. The factors of 9 are 1, 3, and 9. The factors of 15
are 1, 3, 5, and 15. The largest factor that they have in common is 3.
Therefore, the HCF of 9 and 15 is 3.
Another application of
the factors of 9 is in prime factorization. Prime factorization is the process
of expressing a number as the product of its prime factors. The only prime
factor of 9 is 3. We can express 9 as:
9 = 3 × 3
We can do prime
factorization by division and factor tree method also. Here is the prime
factorization of 9 by division method,

∴ 9 = 3 × 3
Here is the prime
factorization of 9 by the factor tree method,

∴ 9 = 3 × 3
Conclusion
The factors of
9 are the numbers that can divide 9 without leaving a remainder. The
factors of 9 are 1, 3, and 9. The factors of 9 have some interesting
properties, such as being odd numbers and having a sum of 13. The factors of 9
have several applications in mathematics, such as finding the highest common
factor and prime factorization.
