2. Steps to find factors of 1071 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 1071 using the division method, follow these steps:

  • Step 1. Start dividing 1071 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 1071, which is 3. Divide 1071 by 3 to obtain the quotient (357).
    1071 ÷ 3 = 357
  • Step 3. Repeat step 1 with the obtained quotient (357).
    357 ÷ 3 = 119
    119 ÷ 7 = 17
    17 ÷ 17 = 1

So, the prime factorization of 1071 is, 1071 = 3 x 3 x 7 x 17.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 1071 as shown below:

So, the prime factorization of 1071 is, 1071 = 3 x 3 x 7 x 17.

3. Find factors of 1071 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 1071 would be the two numbers which, when multiplied, give 1071 as the result.

The following table represents the calculation of factors of 1071 in pairs:

Factor Pair Pair Factorization
1 and 1071 1 x 1071 = 1071
3 and 357 3 x 357 = 1071
7 and 153 7 x 153 = 1071
9 and 119 9 x 119 = 1071
17 and 63 17 x 63 = 1071
21 and 51 21 x 51 = 1071

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 1071. They are called negative pair factors.

Hence, the negative pairs of 1071 would be ( -1 , -1071 ) , ( -3 , -357 ) , ( -7 , -153 ) , ( -9 , -119 ) , ( -17 , -63 ) and ( -21 , -51 ) .

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

  • Every number is a factor of zero (0), since 1071 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, 7, 9, 17, 21, 51, 63, 119, 153, 357, 1071 are exact divisors of 1071.
  • Factors of 1071 are 1, 3, 7, 9, 17, 21, 51, 63, 119, 153, 357, 1071. Each factor divides 1071 without leaving a remainder.
