1. Steps to find factors of 142 using Division Method

Example: Find factors of 142

  • Divide 142 by 1: 142 ÷ 1 : Remainder = 0
  • Divide 142 by 2: 142 ÷ 2 : Remainder = 0
  • Divide 142 by 71: 142 ÷ 71 : Remainder = 0
  • Divide 142 by 142: 142 ÷ 142 : Remainder = 0

Hence, Factors of 142 are 1, 2, 71, and 142

2. Steps to find factors of 142 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 142 using the division method, follow these steps:

  • Step 1. Start dividing 142 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 142, which is 2. Divide 142 by 2 to obtain the quotient (71).
    142 ÷ 2 = 71
  • Step 3. Repeat step 1 with the obtained quotient (71).
    71 ÷ 71 = 1

So, the prime factorization of 142 is, 142 = 2 x 71.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 142 as shown below:

So, the prime factorization of 142 is, 142 = 2 x 71.

3. Find factors of 142 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 142 would be the two numbers which, when multiplied, give 142 as the result.

The following table represents the calculation of factors of 142 in pairs:

Factor Pair Pair Factorization
1 and 142 1 x 142 = 142
2 and 71 2 x 71 = 142

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 142. They are called negative pair factors.

Hence, the negative pairs of 142 would be ( -1 , -142 ) , ( -2 , -71 ) .

How do you explain factors?

In mathematics, a factor is a number or also it can be an algebraic expression that divides another number or any expression completely and that too without leaving any remainder. A factor of a number can be positive or negative.

Properties of factors

  • Each number is a factor of itself. Eg. 142 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, 71, 142 are exact divisors of 142.
  • 1 is a factor of every number. Eg. 1 is a factor of 142.
  • Every number is a factor of zero (0), since 142 x 0 = 0.
