  • Divide 392 by 8: 392 ÷ 8 : Remainder = 0
  • Divide 392 by 14: 392 ÷ 14 : Remainder = 0
  • Divide 392 by 28: 392 ÷ 28 : Remainder = 0
  • Divide 392 by 49: 392 ÷ 49 : Remainder = 0
  • Divide 392 by 56: 392 ÷ 56 : Remainder = 0

  • Divide 392 by 196: 392 ÷ 196 : Remainder = 0
  • Divide 392 by 392: 392 ÷ 392 : Remainder = 0

Hence, Factors of 392 are 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, and 392

2. Steps to find factors of 392 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 392 using the division method, follow these steps:

  • Step 1. Start dividing 392 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 392, which is 2. Divide 392 by 2 to obtain the quotient (196).
    392 ÷ 2 = 196
  • Step 3. Repeat step 1 with the obtained quotient (196).
    196 ÷ 2 = 98
    98 ÷ 2 = 49
    49 ÷ 7 = 7
    7 ÷ 7 = 1

So, the prime factorization of 392 is, 392 = 2 x 2 x 2 x 7 x 7.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 392 as shown below:

So, the prime factorization of 392 is, 392 = 2 x 2 x 2 x 7 x 7.

3. Find factors of 392 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 392 would be the two numbers which, when multiplied, give 392 as the result.

The following table represents the calculation of factors of 392 in pairs:

Factor Pair Pair Factorization
1 and 392 1 x 392 = 392
2 and 196 2 x 196 = 392
4 and 98 4 x 98 = 392
7 and 56 7 x 56 = 392
8 and 49 8 x 49 = 392
14 and 28 14 x 28 = 392

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 392. They are called negative pair factors.

Hence, the negative pairs of 392 would be ( -1 , -392 ) , ( -2 , -196 ) , ( -4 , -98 ) , ( -7 , -56 ) , ( -8 , -49 ) and ( -14 , -28 ) .

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. 392 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 392.
  • Every number is a factor of zero (0), since 392 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, 7, 8, 14, 28, 49, 56, 98, 196, 392 are exact divisors of 392.
  • Factors of 392 are 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392. Each factor divides 392 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392 are all less than or equal to 392.
