Example: Find factors of 208

  • Divide 208 by 1: 208 ÷ 1 : Remainder = 0
  • Divide 208 by 2: 208 ÷ 2 : Remainder = 0
  • Divide 208 by 4: 208 ÷ 4 : Remainder = 0
  • Divide 208 by 8: 208 ÷ 8 : Remainder = 0
  • Divide 208 by 13: 208 ÷ 13 : Remainder = 0
  • Divide 208 by 16: 208 ÷ 16 : Remainder = 0
  • Divide 208 by 26: 208 ÷ 26 : Remainder = 0
  • Divide 208 by 52: 208 ÷ 52 : Remainder = 0
  • Divide 208 by 104: 208 ÷ 104 : Remainder = 0
  • Divide 208 by 208: 208 ÷ 208 : Remainder = 0

Hence, Factors of 208 are 1, 2, 4, 8, 13, 16, 26, 52, 104, and 208

2. Steps to find factors of 208 using Prime Factorization

A prime number is a number that has exactly two factors, 1 and the number itself. Prime factorization of a number means breaking down of the number into the form of products of its prime factors.

There are two different methods that can be used for the prime factorization.

Method 1: Division Method

To find the primefactors of 208 using the division method, follow these steps:

  • Step 1. Start dividing 208 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
  • Step 2. After finding the smallest prime factor of the number 208, which is 2. Divide 208 by 2 to obtain the quotient (104).
    208 ÷ 2 = 104
  • Step 3. Repeat step 1 with the obtained quotient (104).
    104 ÷ 2 = 52
    52 ÷ 2 = 26
    26 ÷ 2 = 13
    13 ÷ 13 = 1

So, the prime factorization of 208 is, 208 = 2 x 2 x 2 x 2 x 13.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 208 as shown below:

So, the prime factorization of 208 is, 208 = 2 x 2 x 2 x 2 x 13.

3. Find factors of 208 in Pairs

Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 208 would be the two numbers which, when multiplied, give 208 as the result.

The following table represents the calculation of factors of 208 in pairs:

Factor Pair Pair Factorization
1 and 208 1 x 208 = 208
2 and 104 2 x 104 = 208
4 and 52 4 x 52 = 208
8 and 26 8 x 26 = 208
13 and 16 13 x 16 = 208

Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 208. They are called negative pair factors.

Hence, the negative pairs of 208 would be ( -1 , -208 ) , ( -2 , -104 ) , ( -4 , -52 ) , ( -8 , -26 ) and ( -13 , -16 ) .

What is the definition of factors?

In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.

Properties of factors

  • Each number is a factor of itself. Eg. 208 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 208.
  • Every number is a factor of zero (0), since 208 x 0 = 0.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Every factor of a number is an exact divisor of that number, example 1, 2, 4, 8, 13, 16, 26, 52, 104, 208 are exact divisors of 208.
  • Factors of 208 are 1, 2, 4, 8, 13, 16, 26, 52, 104, 208. Each factor divides 208 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 8, 13, 16, 26, 52, 104, 208 are all less than or equal to 208.
