1. Steps to find factors of 190 using Division Method

Example: Find factors of 190

  • Divide 190 by 1: 190 ÷ 1 : Remainder = 0
  • Divide 190 by 2: 190 ÷ 2 : Remainder = 0
  • Divide 190 by 5: 190 ÷ 5 : Remainder = 0
  • Divide 190 by 10: 190 ÷ 10 : Remainder = 0
  • Divide 190 by 19: 190 ÷ 19 : Remainder = 0
  • Divide 190 by 38: 190 ÷ 38 : Remainder = 0
  • Divide 190 by 95: 190 ÷ 95 : Remainder = 0
  • Divide 190 by 190: 190 ÷ 190 : Remainder = 0

Hence, Factors of 190 are 1, 2, 5, 10, 19, 38, 95, and 190

2. Steps to find factors of 190 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 190 using the division method, follow these steps:

  • Step 1. Start dividing 190 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 190, which is 2. Divide 190 by 2 to obtain the quotient (95).
    190 ÷ 2 = 95
  • Step 3. Repeat step 1 with the obtained quotient (95).
    95 ÷ 5 = 19
    19 ÷ 19 = 1

So, the prime factorization of 190 is, 190 = 2 x 5 x 19.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 190 as shown below:

So, the prime factorization of 190 is, 190 = 2 x 5 x 19.

3. Find factors of 190 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 190 would be the two numbers which, when multiplied, give 190 as the result.

The following table represents the calculation of factors of 190 in pairs:

Factor Pair Pair Factorization
1 and 190 1 x 190 = 190
2 and 95 2 x 95 = 190
5 and 38 5 x 38 = 190
10 and 19 10 x 19 = 190

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 190. They are called negative pair factors.

Hence, the negative pairs of 190 would be ( -1 , -190 ) , ( -2 , -95 ) , ( -5 , -38 ) and ( -10 , -19 ) .

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

  • Each number is a factor of itself. Eg. 190 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, 5, 10, 19, 38, 95, 190 are exact divisors of 190.
  • 1 is a factor of every number. Eg. 1 is a factor of 190.
  • Every number is a factor of zero (0), since 190 x 0 = 0.
