Definition of factors in math

Multiplying two whole numbers to get the original/product number and a whole number that divides exactly into another number that is called factoring.


Factors of 11 in pairs

11 has only two factors because it is a prime number, it can only be divided by 1 and itself.
 We can find the Factors of 11 by multiplying two whole numbers in a pair to get the result 11.

Multiply by (1)       1 × 11 = 11

There are no more possible pairs so we have all the factors in question.
Factors pairs of 11 = (1×11)

Prime Factorization Of 11

Step 1: - We divide the given number(11) by the smallest prime number that divides the number exactly. We can easily divide 11 by the smallest prime number 11.
 11/11 = 1

 Step 2: - Divide the quotient again by the smallest or the next smallest prime number. We will repeat this process repeatedly until the quotient becomes 1.
11 ÷ 11 = 1

 Prime factors are: -

How many factors of 11?

11 has 2 factors (1, 11) and 4 with negative factors (-1, -11)



How many odd and even factors of 11?

11 has (2) odd factors (1, 11)and (0) even factors ()


How to find the number of odd factors?

Step 1: - At, first find the prime factorization of given number.
11 = 11

 Step 2: - Express them into exponential form.
11 = 11^1

 Step 3: - To find the number of odd factors, you always have to write the exponent (1) in the base of 2. And then add (+1) in all other exponents.
11^1+1
11^2

 Step 4: - Leave the base and multiply all exponents.
2 = 2
Answer. The total number of odd factors is 2.

How to find the sum of odd factors?

The first two steps are the same, factorization of the given number and expressing them in to exponential form.
11 = 11

If you want to find the sum of odd factors, you always have to write (0) in the exponent of 2. And besides them start all bases of the exponent from (0) and move up to maximum power of base and solve them.
11^0 + 11^1
1+11 = 12

 Answer. The sum of odd factors is 12.

How to find the total number of factors?

Step 1: - At, first find the prime factorization of given number.
11 = 11

 Step 2: - Express them into exponential form.
11 = 11^1

 Step 3: - Leave the base (11) and raise all exponent by (+1) one.
1+1 = 2

 Answer: Total number of factor is 2.

How to find the sum of total factors?

The first two steps are the same, factorization of the given number and expressing them in to exponential form.
11 = 11
11 = 11^1

Start all bases of the exponent from (0) and move up to the maximum power of base and solve them.
11^0 + 11^1
1+11 = 12
Answer. The sum of total factors is 12.
