1. Steps to find factors of 715 using Division Method

Example: Find factors of 715

  • Divide 715 by 1: 715 ÷ 1 : Remainder = 0
  • Divide 715 by 5: 715 ÷ 5 : Remainder = 0
  • Divide 715 by 11: 715 ÷ 11 : Remainder = 0
  • Divide 715 by 13: 715 ÷ 13 : Remainder = 0
  • Divide 715 by 55: 715 ÷ 55 : Remainder = 0
  • Divide 715 by 65: 715 ÷ 65 : Remainder = 0
  • Divide 715 by 143: 715 ÷ 143 : Remainder = 0
  • Divide 715 by 715: 715 ÷ 715 : Remainder = 0

Hence, Factors of 715 are 1, 5, 11, 13, 55, 65, 143, and 715

2. Steps to find factors of 715 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 715 using the division method, follow these steps:

  • Step 1. Start dividing 715 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 715, which is 5. Divide 715 by 5 to obtain the quotient (143).
    715 ÷ 5 = 143
  • Step 3. Repeat step 1 with the obtained quotient (143).
    143 ÷ 11 = 13
    13 ÷ 13 = 1

So, the prime factorization of 715 is, 715 = 5 x 11 x 13.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 715 as shown below:

So, the prime factorization of 715 is, 715 = 5 x 11 x 13.

3. Find factors of 715 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 715 would be the two numbers which, when multiplied, give 715 as the result.

The following table represents the calculation of factors of 715 in pairs:

Factor Pair Pair Factorization
1 and 715 1 x 715 = 715
5 and 143 5 x 143 = 715
11 and 65 11 x 65 = 715
13 and 55 13 x 55 = 715

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 715. They are called negative pair factors.

Hence, the negative pairs of 715 would be ( -1 , -715 ) , ( -5 , -143 ) , ( -11 , -65 ) and ( -13 , -55 ) .

What are factors?

In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.

Properties of factors

  • Every number is a factor of zero (0), since 715 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, 5, 11, 13, 55, 65, 143, 715 are exact divisors of 715.
  • Factors of 715 are 1, 5, 11, 13, 55, 65, 143, 715. Each factor divides 715 without leaving a remainder.
