1. Steps to find factors of 545 using Division Method

Example: Find factors of 545

  • Divide 545 by 1: 545 ÷ 1 : Remainder = 0
  • Divide 545 by 5: 545 ÷ 5 : Remainder = 0
  • Divide 545 by 109: 545 ÷ 109 : Remainder = 0
  • Divide 545 by 545: 545 ÷ 545 : Remainder = 0

Hence, Factors of 545 are 1, 5, 109, and 545

2. Steps to find factors of 545 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 545 using the division method, follow these steps:

  • Step 1. Start dividing 545 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 545, which is 5. Divide 545 by 5 to obtain the quotient (109).
    545 ÷ 5 = 109
  • Step 3. Repeat step 1 with the obtained quotient (109).
    109 ÷ 109 = 1

So, the prime factorization of 545 is, 545 = 5 x 109.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 545 as shown below:

So, the prime factorization of 545 is, 545 = 5 x 109.

3. Find factors of 545 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 545 would be the two numbers which, when multiplied, give 545 as the result.

The following table represents the calculation of factors of 545 in pairs:

Factor Pair Pair Factorization
1 and 545 1 x 545 = 545
5 and 109 5 x 109 = 545

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 545. They are called negative pair factors.

Hence, the negative pairs of 545 would be ( -1 , -545 ) , ( -5 , -109 ) .

What are factors?

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

Properties of factors

  • Every factor of a number is an exact divisor of that number, example 1, 5, 109, 545 are exact divisors of 545.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Each number is a factor of itself. Eg. 545 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 545.
