1. Steps to find factors of 178 using Division Method

Example: Find factors of 178

  • Divide 178 by 1: 178 ÷ 1 : Remainder = 0
  • Divide 178 by 2: 178 ÷ 2 : Remainder = 0
  • Divide 178 by 89: 178 ÷ 89 : Remainder = 0
  • Divide 178 by 178: 178 ÷ 178 : Remainder = 0

Hence, Factors of 178 are 1, 2, 89, and 178

2. Steps to find factors of 178 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 178 using the division method, follow these steps:

  • Step 1. Start dividing 178 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 178, which is 2. Divide 178 by 2 to obtain the quotient (89).
    178 ÷ 2 = 89
  • Step 3. Repeat step 1 with the obtained quotient (89).
    89 ÷ 89 = 1

So, the prime factorization of 178 is, 178 = 2 x 89.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 178 as shown below:

So, the prime factorization of 178 is, 178 = 2 x 89.

3. Find factors of 178 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 178 would be the two numbers which, when multiplied, give 178 as the result.

The following table represents the calculation of factors of 178 in pairs:

Factor Pair Pair Factorization
1 and 178 1 x 178 = 178
2 and 89 2 x 89 = 178

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 178. They are called negative pair factors.

Hence, the negative pairs of 178 would be ( -1 , -178 ) , ( -2 , -89 ) .

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. 178 is a factor of itself.
  • 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, 89, 178 are exact divisors of 178.
  • 1 is a factor of every number. Eg. 1 is a factor of 178.
  • Every number is a factor of zero (0), since 178 x 0 = 0.
