1. Steps to find factors of 316 using Division Method

Example: Find factors of 316

  • Divide 316 by 1: 316 ÷ 1 : Remainder = 0
  • Divide 316 by 2: 316 ÷ 2 : Remainder = 0
  • Divide 316 by 4: 316 ÷ 4 : Remainder = 0
  • Divide 316 by 79: 316 ÷ 79 : Remainder = 0
  • Divide 316 by 158: 316 ÷ 158 : Remainder = 0
  • Divide 316 by 316: 316 ÷ 316 : Remainder = 0

Hence, Factors of 316 are 1, 2, 4, 79, 158, and 316

2. Steps to find factors of 316 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 316 using the division method, follow these steps:

  • Step 1. Start dividing 316 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 316, which is 2. Divide 316 by 2 to obtain the quotient (158).
    316 ÷ 2 = 158
  • Step 3. Repeat step 1 with the obtained quotient (158).
    158 ÷ 2 = 79
    79 ÷ 79 = 1

So, the prime factorization of 316 is, 316 = 2 x 2 x 79.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 316 as shown below:

So, the prime factorization of 316 is, 316 = 2 x 2 x 79.

3. Find factors of 316 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 316 would be the two numbers which, when multiplied, give 316 as the result.

The following table represents the calculation of factors of 316 in pairs:

Factor Pair Pair Factorization
1 and 316 1 x 316 = 316
2 and 158 2 x 158 = 316
4 and 79 4 x 79 = 316

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 316. They are called negative pair factors.

Hence, the negative pairs of 316 would be ( -1 , -316 ) , ( -2 , -158 ) and ( -4 , -79 ) .

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. 316 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 316.
  • Every number is a factor of zero (0), since 316 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, 4, 79, 158, 316 are exact divisors of 316.
  • Factors of 316 are 1, 2, 4, 79, 158, 316. Each factor divides 316 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 79, 158, 316 are all less than or equal to 316.
