1. Steps to find factors of 188 using Division Method

Example: Find factors of 188

  • Divide 188 by 1: 188 ÷ 1 : Remainder = 0
  • Divide 188 by 2: 188 ÷ 2 : Remainder = 0
  • Divide 188 by 4: 188 ÷ 4 : Remainder = 0
  • Divide 188 by 47: 188 ÷ 47 : Remainder = 0
  • Divide 188 by 94: 188 ÷ 94 : Remainder = 0
  • Divide 188 by 188: 188 ÷ 188 : Remainder = 0

Hence, Factors of 188 are 1, 2, 4, 47, 94, and 188

2. Steps to find factors of 188 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 188 using the division method, follow these steps:

  • Step 1. Start dividing 188 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 188, which is 2. Divide 188 by 2 to obtain the quotient (94).
    188 ÷ 2 = 94
  • Step 3. Repeat step 1 with the obtained quotient (94).
    94 ÷ 2 = 47
    47 ÷ 47 = 1

So, the prime factorization of 188 is, 188 = 2 x 2 x 47.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 188 as shown below:

So, the prime factorization of 188 is, 188 = 2 x 2 x 47.

3. Find factors of 188 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 188 would be the two numbers which, when multiplied, give 188 as the result.

The following table represents the calculation of factors of 188 in pairs:

Factor Pair Pair Factorization
1 and 188 1 x 188 = 188
2 and 94 2 x 94 = 188
4 and 47 4 x 47 = 188

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 188. They are called negative pair factors.

Hence, the negative pairs of 188 would be ( -1 , -188 ) , ( -2 , -94 ) and ( -4 , -47 ) .

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. 188 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 188.
  • Every number is a factor of zero (0), since 188 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, 47, 94, 188 are exact divisors of 188.
  • Factors of 188 are 1, 2, 4, 47, 94, 188. Each factor divides 188 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 47, 94, 188 are all less than or equal to 188.
