2. Steps to find factors of 2170 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 2170 using the division method, follow these steps:

  • Step 1. Start dividing 2170 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 2170, which is 2. Divide 2170 by 2 to obtain the quotient (1085).
    2170 ÷ 2 = 1085
  • Step 3. Repeat step 1 with the obtained quotient (1085).
    1085 ÷ 5 = 217
    217 ÷ 7 = 31
    31 ÷ 31 = 1

So, the prime factorization of 2170 is, 2170 = 2 x 5 x 7 x 31.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 2170 as shown below:

So, the prime factorization of 2170 is, 2170 = 2 x 5 x 7 x 31.

3. Find factors of 2170 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 2170 would be the two numbers which, when multiplied, give 2170 as the result.

The following table represents the calculation of factors of 2170 in pairs:

Factor Pair Pair Factorization
1 and 2170 1 x 2170 = 2170
2 and 1085 2 x 1085 = 2170
5 and 434 5 x 434 = 2170
7 and 310 7 x 310 = 2170
10 and 217 10 x 217 = 2170
14 and 155 14 x 155 = 2170
31 and 70 31 x 70 = 2170
35 and 62 35 x 62 = 2170

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 2170. They are called negative pair factors.

Hence, the negative pairs of 2170 would be ( -1 , -2170 ) , ( -2 , -1085 ) , ( -5 , -434 ) , ( -7 , -310 ) , ( -10 , -217 ) , ( -14 , -155 ) , ( -31 , -70 ) and ( -35 , -62 ) .

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. 2170 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, 7, 10, 14, 31, 35, 62, 70, 155, 217, 310, 434, 1085, 2170 are exact divisors of 2170.
  • 1 is a factor of every number. Eg. 1 is a factor of 2170.
  • Every number is a factor of zero (0), since 2170 x 0 = 0.
