Solved Factors of 27 Examples
Example 1: Find the common factors of 20 and 27.
Solution:
Factors of 27: 1, 3, 9, 27
Factors of 20: 1, 2, 4, 5, 10, 20.
So, the common factors of 20 and 27 are only number 1.
Hence, 20 and 27 have 1 common factor.
Example 2: John has three boxes. Also, he has some blue, red and orange marbles. Can he arrange an equal number of marbles in each box?
Marbles | Number of marbles |
|---|---|
Oranges | 8 |
Red | 10 |
Blue | 9 |
Solution:
Step 1: Add to find out total number of marbles
8 + 10 + 9 = 27 [Add]
So, John has 27 marbles.
Step 2: Check if the total number of marbles is divisible by the number of boxes.
27 is divisible by 3 as 3 is a factor of 27.
27 \(\div\) 3 = 9 Using the factor pair (3, 9)
Hence, John can arrange an equal number of 9 marbles in each box.
Example 3: How many factor pairs of number 27 exist?
Solution:
All the combination of two factors multiplied together to give a result of 27 is known as factor pairs of 27.
Factors of 27: 1, 2, 3, and 27.
Factor pairs of 27 are (1, 27), (3, 9)
Hence, the number 27 has a total of 2 factor pairs.
Yes, 9 is a factor of 27. As the number 9 divides 27 exactly. It leaves 0 as the remainder. So, 9 is a factor of 27.
Yes, 27 is a composite number as it has factors other than one and itself. It has factors such as 3 and 9 other than 1 and 27.
The factors of 27 are 1, 3, 9, 27.
So, the least factor of 27 is 1 and the greatest factor is 27 itself.
The factors of 27 are 1, 3, 9 and 27.
Hence, the sum of all the factors of 27 is
= 1 + 3 + 9 + 27
= 40
Hence, the sum is 40.
Factors of 27 are 1, 3, 9, and 27.
Factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.
So, the common factors of 27 and 24 are 1 and 3.
