Answer 2

125 is a perfect cube number. 125 can be expressed as a sum of two squares in two different ways, i.e. 125 = 102 + 52 or 112+ 22. Let us explore more about the factors of 125! In this chapter, we will learn about the factors of 125, the factors of 125 in pairs along with some interactive examples on the prime factors of 125.

Prime Factorization of 125: 5 × 5 × 5

What Are the Factors of 125?

Factors of 125 are the numbers which exactly divide it and give the remainder as 0.  

When you multiply any two whole numbers with each other and get 125 as the answer, you can say that both the numbers will be the factors of 125.

1× 125 = 125 and 5 ×  25 = 125; thus, the factors of 125 are 1, 5, 25, and 125.

How to Calculate the Factors of 125?

Let's begin calculating the factors of 125, starting with the whole number 1.  

Divide 125 with this number. Is the remainder 0? Yes! So, we will get: 125 ÷ 1 = 125

The next number is 2. 125 ÷ 2 = 62, Remainder = 1

We will not include those numbers which leave a remainder on division.

The next whole number is 5. Now, divide 125 with this number. 125 ÷ 5 = 25, Remainder = 0

Proceeding in a similar manner, we obtain the factors of 125 as 1, 5, 25 and 125.

Factors of 225: The factors of 225 are 1, 3, 5, 9, 15, 25, 45, 75 and 225.  

Factors of 75: The factors of 75 are 1, 3, 5, 15, 25, and 75.

Factors of 81: The factors of 81 are 1, 3, 9, 27, and 81.

Factors of 125 by Prime Factorization

Prime factorization means to express a composite number as the product of its prime factors.  

We can get the prime factors using the factor tree as shown in the figure below.

The prime factorization of 125 can also be represented using the upside-down division method.

prime factorization of 125

Let us express 125 in terms of the product of its prime factors as 5 × 5 × 5 or in the exponent form as 53. Now that we have done the prime factorization of our number, we can multiply them factors and get the other possible composite factors. Can you try and find out if all the factors are covered?

Factors of 125 in Pairs

The pair of numbers which gives 125 when multiplied are known as the factor pairs of 125. We know that 1 × 125 = 125 and 5 × 25 = 25. Therefore, the distinct factors of 125 in pairs are (1, 125) and (5, 25).

factor pairs of 125

Pair factors can be either positive or negative but they cannot be a fraction or a decimal number. Hence, we can have negative factor pairs of 125 as (-1, -125) and (-5, -25).

Important Notes:

When you divide a number by its factor, the quotient of the division is also a factor.

Factors of 125 are 1, 5, 25, and 125.

125 is the cube of 5.

 

Factors of 125 Solved Examples
