## What Are the Factors of 148?

The factors of 148 are 1, 2, 4, 37, 74, and 148. All of these numbers are the factors as they do not leave any remainder when divided by 148.

The factors of 148 are classified as prime numbers and composite numbers. The prime factors of the number 148 can be determined using the technique of prime factorization.

## How To Find the Factors of 148?

You can find the factors of 148 by using the rules of divisibility. The rule of divisibility states that any number when divided by any other natural number then it is said to be divisible by the number if the quotient is the whole number and the resulting remainder is zero.

To find the factors of 148, create a list containing the numbers that are exactly divisible by 148 with zero remainders. One important thing to note is that 1 and 148 are the 148’s factors as every natural number has 1 and the number itself as its factor.

1 is also called the universal factor of every number. The factors of 148 are determined as follows:

$\dfrac{148}{1} = 148$

$\dfrac{148}{2} = 74$

$\dfrac{148}{4} = 37$

$\dfrac{148}{37} = 4$

$\dfrac{148}{74} = 2$

$\dfrac{148}{148} = 1$

Therefore, 1, 2, 4, 37, 74, and 148 are the factors of X.

### Total Number of Factors of 148

For 148 there are 6 positive factors and 6 negative ones. So in total, there are 12 factors of 148.

To find the total number of factors of the given number, follow the procedure mentioned below:

1. Find the factorization of the given number.
2. Demonstrate the prime factorization of the number in the form of exponent form.
3. Add 1 to each of the exponents of the prime factor.
4. Now, multiply the resulting exponents together. This obtained product is equivalent to the total number of factors of the given number.

By following this procedure the total number of factors of 148 is given as:

$Factorization= 1 \times 2^{2} \times 37$

The exponent of 1 and 37 is 1 and the factor of 2 is 2.

Adding 1 to each and multiplying them together results in 12.

Therefore, the total number of factors of 148 is 12, where 6 are positive factors and 6 are negative.

### Important Notes

Here are some important points that must be considered while finding the factors of any given number:

• The factor of any given number must be a whole number.
• The factors of the number cannot be in the form of decimals or fractions.
• Factors can be positive as well as negative.
• Negative factors are the additive inverse of the positive factors of a given number.
• The factor of a number cannot be greater than that number.
• Every even number has 2 as its prime factor which is the smallest prime factor.

## Factors of 148 by Prime Factorization

The number 148 is a composite number. Prime factorization is a useful technique for finding the number’s prime factors and expressing the number as the product of its prime factors.

Before finding the factors of 148 using prime factorization, let us find out what prime factors are. Prime factors are the factors of any given number that are only divisible by 1 and themselves.

To start the prime factorization of 148, start dividing by its smallest prime factor. First, determine that the given number is either even or odd. If it is an even number, then 2 will be the smallest prime factor.

Continue splitting the quotient obtained until 1 is received as the quotient. The prime factorization of 148 can be expressed as:

$148 = 2^{2} \times 37$

## Factors of 148 in Pairs

The factor pairs are the duplet of numbers that when multiplied together result in the factorized number. Depending upon the total number of factors of the given numbers, factor pairs can be more than one.

For 148, the factor pairs can be found as:

$1 \times 148 = 148$

$2 \times 74 = 148$

$4 \times 37=148$

The possible factor pairs of 148 are given as (1, 148), (2, 74), and (4, 37).

All these numbers in pairs, when multiplied, give 148 as the product.

The negative factor pairs of 148 are given as:

$-1 \times -148 = 148$

$-2 \times -74 = 148$

$-4 \times -37 = 148$

It is important to note that in negative factor pairs, the minus sign has been multiplied by the minus sign due to which the resulting product is the original positive number. Therefore, -1, -2, -4, -37, -74, and -148 are called negative factors of 148.

The list of all the factors of 148 including positive as well as negative numbers is given below.
