What are the Factors of 432?

The factors of 432 are the numbers that divide 432 completely without leaving any remainder. 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216 and 432 are the factors of 432.

How to Calculate the Factors of 432?

Determine half of 432. It is 216.
Using the divisibility rules, keep dividing 432 from 1 to 216. They form the divisors of 432. Obtain the quotient.
The divisors and the quotient form the factors of 432.
While we are doing this, we observe that 432 is not divisible by 5, 7, 10, 11, 13, 14 and 15
While we are dividing by 18, we reach the level of obtaining all the factors of 432.

432 ÷ 1 = 432

432 ÷ 2 = 216

432 ÷ 3 = 144

432 ÷ 4 = 108

432 ÷ 6 = 72

432 ÷ 8 = 54

432 ÷ 9 = 48

432 ÷ 12 = 36

432 ÷ 16 = 27

432 ÷ 18 = 24

To understand the concept of finding factors by prime factorization better, let us take a few more examples.

Factors of 360: The factors of 360 are 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180 and 360.
Factors of 108: The factors of 108 are 1, 2, 3 , 4, 6, 9, 12, 18, 27, 36, 54 and 108.
Factors of 180: The factors of 180 are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90 and 180.
Factors of 112: The factors of 112 are 1, 2, 4, 7, 8, 14, 16, 28, 56, and 112.
Factors of 216: The factors of 216 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108 and 216.

Factors of 432 by Prime Factorization

We obtain the prime factors by using prime factorization. This can be followed using factor tree or upside-division method.

Step 1: Divide 432 by its smallest prime factor 2. We get its composite factor-pair as 216.
Step 2: Divide 216 by its smallest prime factor, 2. The composite factor-pair is 108
Step 3: Keep dividing each time by the smallest prime factor and continue until we reach the level where no more factorization can be done.
This way we express 432 as a product of its prime factors 2 and 3.
432 = 2 × 2 × 2 × 2 × 3 × 3 × 3 = 2⁴ × 3³

Factors of 432 in Pairs

The factors that pair up to give the product 432 are the factors of 432 in pairs. We have 10 such distinct ordered pairs. They are (1, 432), (2, 216), (3, 144), (4, 108), (6, 72), (8, 54), (9, 48), (12, 36), (16,27) and (18, 24).

Important Notes:

There are 20 factors of 432.
The prime factors of 432 are 2 and 3.
The prime factorization of 432 is 2⁴× 3³.

Tips and Tricks

Do the prime factorization of 432 and obtain it as 2⁴× 3³. Add 1 to each exponent and multiply them. Here we have (4+1) × (3+1) = 5 × 4 = 20. This product helps us determine the total number of factors of 432.
Another trick is multiply 2 × 2 × 2 × 2 × 3 × 3 × 3 in all the possible ways to get the composite factors.

Example 1: Andrew decides to buy 432 cars. He finds 2 packs at the wholesale shop. 216 toy cars at $18 and 432 toy cars at $36. Which is the better deal for him?

Solution:

Packs Number of Toy Cars Cost of the pack

Pack 1 216 $18

Pack 2 432 $36

Let us determine the cost of each toy car in both the packs.
We need to find the missing factor in each case.
Cost of each toy car in pack 1 is 216 ÷ 18 = $12.
Here the cost of 432 cars = $24
Cost of each toy car in pack 2 is 432 ÷ 16 = $27
$24 < $27. Therefore getting 2 packs of pack 1 is the better deal for Andrew.
Example 2: If Amelia sent 432 messages in all in 18 days to her friend, find the messages that she had sent on an average in a day?

Solution:

___ of messages per day × 18 days = Total 432 messages
____ × 18 = 432
Finding the missing factor-pair of 18 that makes 432, we find that
16 × 18 = 432
Therefore, the number of messages sent on an average in a day = 16
