What are the factors of 10?
The factors of 10 are the numbers that exactly divide 10.
You can observe that the numbers 1, 2, 5, and 10 on dividing 10 leaves the remainder as 0.
This means 1, 2, 5, and 10 exactly divide the number 10
They are the factors of 10
Important Notes
 Factors of a number are always less than or equal to the original number.
 The remainder obtained on dividing a number by its factor is always 0.
 Every composite number can be uniquely expressed as the product of its prime factors.
 Prime numbers have only two factors.
How to Calculate the Factors of 10?
Let's find the pair of two numbers whose product is equal to 10
2 x 5 = 10
10 x 1 = 10
So, we have only these two pairs of numbers that give us the product 10
Factors of 10 are the numbers when multiplied together, give the product as 10
So, the factors of 10 are 1, 2, 5, and 10.
Factors of 10 by Prime Factorization
Prime factorization is a way of expressing a number as a product of its prime factors.
10 is a composite number.
So, it can be written as the product of prime numbers.
To find the prime factors, we will break down the number 10 into the set of primes which when multiplied together gives the result as 10.
The only prime numbers that exactly divide 10 are 2 and 5
Factors of 10 in Pairs
The pair of numbers which gives 10 when multiplied are known as factor pairs of 104
Following are the factors of 10 in pairs.
Product form of 10  Pair factor 
1 x 10 = 10  (1,10) 
2 x 5 = 10  (2,5) 
Pairs of factors of 10 are: (1,10), (2,5).
Let's have a look at the negative pair factors of 10
So, if we consider negative integers, then both the numbers in the pair factors will be negative.
It is possible to have negative pair factors as well because the product of two negative numbers also gives a positive number.
So, we can have factor pairs of 10 as (1,10) ; (2,5).
Solved Examples

Example 1
Mia and Rene are playing with circles.
Rene writes the factors of 10 in the red circle and Mia writes the factors of 20 in the blue circle.
Can you help them?
Solution
Factors of 10 are 1, 2, 5, and 10
Factors of 20 are 1, 2, 4, 5, 10, and 20
The common factors of 10 and 20 are 1, 2, 5, and 10

Example 2
Aaron is asked to find the missing numbers in the factor trees of 18, 9, and 12
Can you help him complete all the factor trees?
Are there any common factors of 9 and 10?
Solution
Let's find the missing factor in the factor tree of 18
Pair 9 and 2 forms a factor pair of 18
So, 9 is a missing factor of 18
Now, let's find the missing factor in the factor tree of 12
The missing number is a factor of 4 as well.
Pair 2 and 2 forms a factor pair of 4
So, 2 is a missing factor of 12
Let's see the factors of 9 and 10
Factors of 9: 1, 3, 9
Factors of 10: 1, 2, 5, 10
So, 1 is a common factor of 9 and 10
Therefore, The missing factors of 18 and 12 are shown in the factor tree. The common factor of 9 and 10 is 1.

Example 3: How many factors are there for 10?
Solution:
The factors of 10 are 1, 2, 5, 10. Therefore, 10 has 4 factors.
