1. Steps to find factors of 195 using Division Method

Example: Find factors of 195

  • Divide 195 by 1: 195 ÷ 1 : Remainder = 0
  • Divide 195 by 3: 195 ÷ 3 : Remainder = 0
  • Divide 195 by 5: 195 ÷ 5 : Remainder = 0
  • Divide 195 by 13: 195 ÷ 13 : Remainder = 0
  • Divide 195 by 15: 195 ÷ 15 : Remainder = 0
  • Divide 195 by 39: 195 ÷ 39 : Remainder = 0
  • Divide 195 by 65: 195 ÷ 65 : Remainder = 0
  • Divide 195 by 195: 195 ÷ 195 : Remainder = 0

Hence, Factors of 195 are 1, 3, 5, 13, 15, 39, 65, and 195

2. Steps to find factors of 195 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 195 using the division method, follow these steps:

  • Step 1. Start dividing 195 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 195, which is 3. Divide 195 by 3 to obtain the quotient (65).
    195 ÷ 3 = 65
  • Step 3. Repeat step 1 with the obtained quotient (65).
    65 ÷ 5 = 13
    13 ÷ 13 = 1

So, the prime factorization of 195 is, 195 = 3 x 5 x 13.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 195 as shown below:

So, the prime factorization of 195 is, 195 = 3 x 5 x 13.

3. Find factors of 195 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 195 would be the two numbers which, when multiplied, give 195 as the result.

The following table represents the calculation of factors of 195 in pairs:

Factor Pair Pair Factorization
1 and 195 1 x 195 = 195
3 and 65 3 x 65 = 195
5 and 39 5 x 39 = 195
13 and 15 13 x 15 = 195

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 195. They are called negative pair factors.

Hence, the negative pairs of 195 would be ( -1 , -195 ) , ( -3 , -65 ) , ( -5 , -39 ) and ( -13 , -15 ) .

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 number is a factor of zero (0), since 195 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, 3, 5, 13, 15, 39, 65, 195 are exact divisors of 195.
  • Factors of 195 are 1, 3, 5, 13, 15, 39, 65, 195. Each factor divides 195 without leaving a remainder.
