1. Steps to find factors of 148 using Division Method

Example: Find factors of 148

  • Divide 148 by 1: 148 ÷ 1 : Remainder = 0
  • Divide 148 by 2: 148 ÷ 2 : Remainder = 0
  • Divide 148 by 4: 148 ÷ 4 : Remainder = 0
  • Divide 148 by 37: 148 ÷ 37 : Remainder = 0
  • Divide 148 by 74: 148 ÷ 74 : Remainder = 0
  • Divide 148 by 148: 148 ÷ 148 : Remainder = 0

Hence, Factors of 148 are 1, 2, 4, 37, 74, and 148

2. Steps to find factors of 148 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 148 using the division method, follow these steps:

  • Step 1. Start dividing 148 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 148, which is 2. Divide 148 by 2 to obtain the quotient (74).
    148 ÷ 2 = 74
  • Step 3. Repeat step 1 with the obtained quotient (74).
    74 ÷ 2 = 37
    37 ÷ 37 = 1

So, the prime factorization of 148 is, 148 = 2 x 2 x 37.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 148 as shown below:

So, the prime factorization of 148 is, 148 = 2 x 2 x 37.

3. Find factors of 148 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 148 would be the two numbers which, when multiplied, give 148 as the result.

The following table represents the calculation of factors of 148 in pairs:

Factor Pair Pair Factorization
1 and 148 1 x 148 = 148
2 and 74 2 x 74 = 148
4 and 37 4 x 37 = 148

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 148. They are called negative pair factors.

Hence, the negative pairs of 148 would be ( -1 , -148 ) , ( -2 , -74 ) and ( -4 , -37 ) .

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. 148 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 148.
  • Every number is a factor of zero (0), since 148 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, 37, 74, 148 are exact divisors of 148.
  • Factors of 148 are 1, 2, 4, 37, 74, 148. Each factor divides 148 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 37, 74, 148 are all less than or equal to 148.
