What are the composite factors of 24?
- 4, 6, 8, 12, 24
- 4, 5
- 4, 9
- None of the above
Hint:
When we factorise a number and get two or more factors, such number is known as a composite number.
Composite numbers are divisible by atleast one digit (other than 1).
The correct answer is: 4, 6, 8, 12, 24
To find- Composite factors of 24.
Solution-
To find composite factors of 24, we will first find all the factors of 24.
Factors of 24- 1, 2, 3, 4, 6, 8, 12, 24
Out of the 8 factors of 24 listed above, 4, 6, 8, 12 and 24 are composite numbers because they are divisible by more than 1 number as mentioned below-
4- 1, 2
6- 1, 2, 3
8- 1, 2, 4
12- 1, 2, 3, 4, 6
24- 1, 2, 3, 4, 6, 8, 12, 24
Hence, 4, 6, 8, 12 and 24 are the composite factors of 24.
Final Answer- 'Option a' i.e. "4, 6, 8, 12, 24".
