Hint: The given question requires us to find out the factors of given number. A number's factor is defined as a number that divides the original number evenly or precisely. Each prime number has only two factors: 1 and the number itself, while each composite number has more than two factors, which will include prime factors.
Complete step-by-step answer:
An algebraic expression's factors are the values that can be used to divide the given expression. Fractions are not considered to be factors of a given expression. Negative numbers are also included in factors since the product of two negative numbers is a positive number.
We can find out the factors of a given number by various methods. Let us find the factors of with different methods.
Method 1: Use multiplication tables in case of small numbers.
With the help of the multiplication table, we have to find all the numbers whose product will be . Hence, we will get:
Moreover, , and
Therefore,
Positive factors of are and &
Negative factors are and .
Method 2: Using division method
In this case, the number is divided by prime numbers till we get a quotient in the prime number or .
Here is divided by prime numbers to arrive at the solution and all the quotients will form the factor of . Moreover, the product of divisor will also form part of factor i.e. , , and .
Therefore,
Positive factors of are and &
Negative factors are and .
Method 3: Prime Factorization Method
can be written in form of prime factors as:
Now we just have to multiply the multiples i.e. , , and .
Hence,
Positive factors of are and &
Negative factors are and .
Note: In case of large numbers, division method is preferable.
In the given question, we can write positive factor pair of as follows:
We can write negative factors in a similar manner.
