2. Steps to find factors of 2646 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 2646 using the division method, follow these steps:

  • Step 1. Start dividing 2646 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 2646, which is 2. Divide 2646 by 2 to obtain the quotient (1323).
    2646 ÷ 2 = 1323
  • Step 3. Repeat step 1 with the obtained quotient (1323).
    1323 ÷ 3 = 441
    441 ÷ 3 = 147
    147 ÷ 3 = 49
    49 ÷ 7 = 7
    7 ÷ 7 = 1

So, the prime factorization of 2646 is, 2646 = 2 x 3 x 3 x 3 x 7 x 7.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 2646 as shown below:

So, the prime factorization of 2646 is, 2646 = 2 x 3 x 3 x 3 x 7 x 7.

3. Find factors of 2646 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 2646 would be the two numbers which, when multiplied, give 2646 as the result.

The following table represents the calculation of factors of 2646 in pairs:

Factor Pair Pair Factorization
1 and 2646 1 x 2646 = 2646
2 and 1323 2 x 1323 = 2646
3 and 882 3 x 882 = 2646
6 and 441 6 x 441 = 2646
7 and 378 7 x 378 = 2646
9 and 294 9 x 294 = 2646
14 and 189 14 x 189 = 2646
18 and 147 18 x 147 = 2646
21 and 126 21 x 126 = 2646
27 and 98 27 x 98 = 2646
42 and 63 42 x 63 = 2646
49 and 54 49 x 54 = 2646

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 2646. They are called negative pair factors.

Hence, the negative pairs of 2646 would be ( -1 , -2646 ) , ( -2 , -1323 ) , ( -3 , -882 ) , ( -6 , -441 ) , ( -7 , -378 ) , ( -9 , -294 ) , ( -14 , -189 ) , ( -18 , -147 ) , ( -21 , -126 ) , ( -27 , -98 ) , ( -42 , -63 ) and ( -49 , -54 ) .

How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

Properties of factors

  • Each number is a factor of itself. Eg. 2646 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, 3, 6, 7, 9, 14, 18, 21, 27, 42, 49, 54, 63, 98, 126, 147, 189, 294, 378, 441, 882, 1323, 2646 are exact divisors of 2646.
  • 1 is a factor of every number. Eg. 1 is a factor of 2646.
  • Every number is a factor of zero (0), since 2646 x 0 = 0.
