How To Find Factors of 48 Through Division Method?

You can determine the factors of 48, using the division method. This approach requires you to multiply a sequence of natural integers by 48. The numbers that divide the 48 completely without leaving any remainder are known as 48 factors. The detailed steps for finding factors of 48 using the division method are as below:

  • 48 ÷ 1 = 48
  • 48 ÷ 2 = 24
  • 48 ÷ 3 = 16
  • 48 ÷ 4 = 12
  • 48 ÷ 6 = 8
  • 48 ÷ 8 = 6
  • 48 ÷ 12 = 4
  • 48 ÷ 16 = 3
  • 48 ÷ 24 =2
  • 48 ÷ 48 = 1

Therefore, we can see that 1, 2, 3, 4, 6, 12, 16, 24, and 48 are the numbers that do not leave any remainder when divided by 48. Hence, the factors of 48 are 1, 2, 3, 4, 6, 12, 16, 24, and 48. 

What Is the Prime Factorisation of 48?

For finding the prime factorization of a number, we need to check if the given number is a prime number. If the given number is a prime number, then it has only two factors: 1 and the number itself. If the given number is a composite number, then it has more than two factors.

Since 48 is the composite number, we have more than two factors. Hence, we can use the prime factorization method to find the factors of 48.
The steps to find prime factors of 48 using the prime factorization method are given below:

  • Step 1: Divide the number 48 by the smallest prime number that is divisible by 48. Hence the smallest prime number that is divisible by 48 is 2.
    • 48 ÷ 2 = 24
  • Step 2: Now, divide the number 24 (quotient) by the smallest prime number which is 2.
    • 24 ÷ 2 = 12
  • Step 3: Divide the quotient by 2 repeatedly until you get the number prime number as the quotient.
    • 12 ÷ 2 = 6
    • 6 ÷ 2 = 3
  • Step 4: Now we got 3 as the quotient. Dividing 3 with 3 gives us 1.
    • 3 ÷ 3 = 1

The quotient is 1. Since 1 cannot be divided further, the prime factors of 48 are 2 X 2 X 2 X 2 X 3 or 24 X 3. We can also write it down as 2 and 3, as both of them are prime numbers.

The prime factorization for 48 can be represented below:

What is the Factor Tree of 48?

Students can also use the factor tree to find the prime factors of 48. In this method, we will place the number 48 at the top of the factor tree. Now, as part of the branches, we will write down any set of pair factors of the given number (48). Now, again, we will split the pair of factors into factors. This process will be continued until the branches become prime numbers. Now, circling all the prime numbers will give us the prime factors of 48.

  • Step 1: Let’s place the number 48 at the top of the factor tree and write down 48 in pairs, that is, 2 and 24.
  • Step 2: Since 2 is a prime number, we can no longer separate it. We will now divide 24 into 2 and 12.
  • Step 3: As we can see, 2 is a prime number but 12 is not, so we will split 12 into 1 and 6.
  • Step 4: Now again, we will leave 2 as it is because it is a prime number, but we will break 6 into 2 and 3.
  • Step 5: We can see that 2 and 3 are both prime numbers. The branches in the factor tree will now be all the prime numbers.

Hence, circling all the branches, 24 X 3 or 2 X 2 X 2 X 2 X 3= 48, which are 48 prime factors.

There are many ways in which we can write the factor tree of 48. Below is an image representation of the factor tree of 48, choosing 6 and 8 as pair factors of 48.
