1. Steps to find factors of 54 using Division Method

Example: Find factors of 54

  • Divide 54 by 1: 54 ÷ 1 : Remainder = 0
  • Divide 54 by 2: 54 ÷ 2 : Remainder = 0
  • Divide 54 by 3: 54 ÷ 3 : Remainder = 0
  • Divide 54 by 6: 54 ÷ 6 : Remainder = 0
  • Divide 54 by 9: 54 ÷ 9 : Remainder = 0
  • Divide 54 by 18: 54 ÷ 18 : Remainder = 0
  • Divide 54 by 27: 54 ÷ 27 : Remainder = 0
  • Divide 54 by 54: 54 ÷ 54 : Remainder = 0

Hence, Factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54

2. Steps to find factors of 54 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 54 using the division method, follow these steps:

  • Step 1. Start dividing 54 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 54, which is 2. Divide 54 by 2 to obtain the quotient (27).
    54 ÷ 2 = 27
  • Step 3. Repeat step 1 with the obtained quotient (27).
    27 ÷ 3 = 9
    9 ÷ 3 = 3
    3 ÷ 3 = 1

So, the prime factorization of 54 is, 54 = 2 x 3 x 3 x 3.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 54 as shown below:

So, the prime factorization of 54 is, 54 = 2 x 3 x 3 x 3.

3. Find factors of 54 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 54 would be the two numbers which, when multiplied, give 54 as the result.

The following table represents the calculation of factors of 54 in pairs:

Factor Pair Pair Factorization
1 and 54 1 x 54 = 54
2 and 27 2 x 27 = 54
3 and 18 3 x 18 = 54
6 and 9 6 x 9 = 54

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 54. They are called negative pair factors.

Hence, the negative pairs of 54 would be ( -1 , -54 ) , ( -2 , -27 ) , ( -3 , -18 ) and ( -6 , -9 ) .

How can we define factors?

In mathematics, a factor is a number which divides into another number exactly, without leaving any remainder. A factor of a number can be positive of negative.

Properties of factors

  • Each number is a factor of itself. Eg. 54 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, 3, 6, 9, 18, 27, 54 are exact divisors of 54.
  • 1 is a factor of every number. Eg. 1 is a factor of 54.
  • Every number is a factor of zero (0), since 54 x 0 = 0.
