1. Steps to find factors of 425 using Division Method

Example: Find factors of 425

  • Divide 425 by 1: 425 ÷ 1 : Remainder = 0
  • Divide 425 by 5: 425 ÷ 5 : Remainder = 0
  • Divide 425 by 17: 425 ÷ 17 : Remainder = 0
  • Divide 425 by 25: 425 ÷ 25 : Remainder = 0
  • Divide 425 by 85: 425 ÷ 85 : Remainder = 0
  • Divide 425 by 425: 425 ÷ 425 : Remainder = 0

Hence, Factors of 425 are 1, 5, 17, 25, 85, and 425

2. Steps to find factors of 425 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 425 using the division method, follow these steps:

  • Step 1. Start dividing 425 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 425, which is 5. Divide 425 by 5 to obtain the quotient (85).
    425 ÷ 5 = 85
  • Step 3. Repeat step 1 with the obtained quotient (85).
    85 ÷ 5 = 17
    17 ÷ 17 = 1

So, the prime factorization of 425 is, 425 = 5 x 5 x 17.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 425 as shown below:

So, the prime factorization of 425 is, 425 = 5 x 5 x 17.

3. Find factors of 425 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 425 would be the two numbers which, when multiplied, give 425 as the result.

The following table represents the calculation of factors of 425 in pairs:

Factor Pair Pair Factorization
1 and 425 1 x 425 = 425
5 and 85 5 x 85 = 425
17 and 25 17 x 25 = 425

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 425. They are called negative pair factors.

Hence, the negative pairs of 425 would be ( -1 , -425 ) , ( -5 , -85 ) and ( -17 , -25 ) .

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 factor of a number is an exact divisor of that number, example 1, 5, 17, 25, 85, 425 are exact divisors of 425.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Each number is a factor of itself. Eg. 425 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 425.
