2. Steps to find factors of 2100 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 2100 using the division method, follow these steps:

  • Step 1. Start dividing 2100 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 2100, which is 2. Divide 2100 by 2 to obtain the quotient (1050).
    2100 ÷ 2 = 1050
  • Step 3. Repeat step 1 with the obtained quotient (1050).
    1050 ÷ 2 = 525
    525 ÷ 3 = 175
    175 ÷ 5 = 35
    35 ÷ 5 = 7
    7 ÷ 7 = 1

So, the prime factorization of 2100 is, 2100 = 2 x 2 x 3 x 5 x 5 x 7.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 2100 as shown below:

So, the prime factorization of 2100 is, 2100 = 2 x 2 x 3 x 5 x 5 x 7.

3. Find factors of 2100 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 2100 would be the two numbers which, when multiplied, give 2100 as the result.

The following table represents the calculation of factors of 2100 in pairs:

Factor Pair Pair Factorization
1 and 2100 1 x 2100 = 2100
2 and 1050 2 x 1050 = 2100
3 and 700 3 x 700 = 2100
4 and 525 4 x 525 = 2100
5 and 420 5 x 420 = 2100
6 and 350 6 x 350 = 2100
7 and 300 7 x 300 = 2100
10 and 210 10 x 210 = 2100
12 and 175 12 x 175 = 2100
14 and 150 14 x 150 = 2100
15 and 140 15 x 140 = 2100
20 and 105 20 x 105 = 2100
21 and 100 21 x 100 = 2100
25 and 84 25 x 84 = 2100
28 and 75 28 x 75 = 2100
30 and 70 30 x 70 = 2100
35 and 60 35 x 60 = 2100
42 and 50 42 x 50 = 2100

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 2100. They are called negative pair factors.

Hence, the negative pairs of 2100 would be ( -1 , -2100 ) , ( -2 , -1050 ) , ( -3 , -700 ) , ( -4 , -525 ) , ( -5 , -420 ) , ( -6 , -350 ) , ( -7 , -300 ) , ( -10 , -210 ) , ( -12 , -175 ) , ( -14 , -150 ) , ( -15 , -140 ) , ( -20 , -105 ) , ( -21 , -100 ) , ( -25 , -84 ) , ( -28 , -75 ) , ( -30 , -70 ) , ( -35 , -60 ) and ( -42 , -50 ) .

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. 2100 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 2100.
  • Every number is a factor of zero (0), since 2100 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, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 25, 28, 30, 35, 42, 50, 60, 70, 75, 84, 100, 105, 140, 150, 175, 210, 300, 350, 420, 525, 700, 1050, 2100 are exact divisors of 2100.
  • Factors of 2100 are 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 25, 28, 30, 35, 42, 50, 60, 70, 75, 84, 100, 105, 140, 150, 175, 210, 300, 350, 420, 525, 700, 1050, 2100. Each factor divides 2100 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 25, 28, 30, 35, 42, 50, 60, 70, 75, 84, 100, 105, 140, 150, 175, 210, 300, 350, 420, 525, 700, 1050, 2100 are all less than or equal to 2100.
