Factors of 125

The numbers which can evenly divide 125 are the factors of 125. 1, 5, 25, 125 are the factors of 125.

 

Negative factors of 125: The negative factors of 125 are the negative counterparts of the positive factors. -1, -5, -25, -125 are the negative factors of 125.

 

Prime factors of 125: A prime number is a number which has only two factors, i.e., 1 and the number itself.
5 is the prime factor of 125.

 

Prime factorization of 125: The process of splitting a number into smaller prime numbers is prime factorization. Here, the product of prime numbers is the number itself.

The prime factorization of 125 is 5³
 

Factors of a number is a number which can evenly divide the number. Some methods which are used to find the factor of a 125 are,

 

• Multiplication method

 

• Division method

 

• Prime factors and prime factorization

 

• Factor tree
   

In the multiplication method a pair of numbers are identified, the product of multiplying the number is 125. 

 

Step 1: Find the number whose product is 125.

 

1 × 125 = 125

5 × 25 = 125

 

Step 2: List them as pairs

 

The pair of factors are (1, 125), (5, 25)
 

In the division method, we need to check which number can evenly divide 125. 

 

Let’s check the factors of 125 using division method

 

125 ÷ 1 = 125

125 ÷ 5 = 25

So, the factors are 1, 5, 25, and 125.
 

Prime numbers are the numbers which have only two factors. The process of breaking down a large number into a smaller prime number is prime factorization. 

To find the factors of a number prime factorization, we need to follow these steps

 

Step 1: The given number needs to be divided with the smallest prime number.

 

Step 2: Now, we need to divide the remainder in step 1 with the prime number. The process is continued till the remainder is a prime number.

 
 Let's use the prime factorization method to find the factors of 125.

 

The prime factor of 125 is 5.

 

2, 3, 5, 7, 11, 13, 17,… are the prime numbers. 

Step 1: Checking the divisibility by 2: 125 is an odd number, so, not divisible by 2.

Checking the divisibility by 3: As the sum of 125 is 8, 8 is not divisible by3. So 125 is not divisible by 3. 

 

Checking divisibility by 5: Dividing 125 with 5

 

125 ÷ 5 = 25

 

Step 2: now, the remainder is 25

 

Checking the divisibility by 5: 25 ÷ 5 = 5

 

Step 3: Now, the remainder is 5 which is a prime number.

 

So, the factors of 125 are 1, 5, 25, 125.

The Pictorial representation of factors of a number. It is in the form of a tree where the given number is split into branches which represent all the factors. 

 

The factor tree of 125:

 

A pair of factors of a number. The product of those numbers is the number itself. Factor pairs can be both positive and negative.

 

Positive pair factors: (1, 125), (5, 25).

Negative pair factors: (-1, -125), (-5, -25).
 

 

• Prime number: Any numbers which has only two factors are the prime numbers

 

• Composite numbers: The number which has more than two factors

 

• Remainder: The value left after dividing a number by another number. For example, 1 is the remainder when we divide 5 by 2.

 

• Product: The product of any number is the result of multiplying the number.
