Which of them is composite number?a)6b)5c)7d)3Correct answer is option...
Composite numbers are positive integers that have more than two factors. In other words, they are numbers that can be divided evenly by more than just 1 and themselves. Let's examine each option to determine if it is a composite number or not.
a) 6
- Factors of 6: 1, 2, 3, 6
- 6 can be divided evenly by 1, 2, 3, and 6.
- Therefore, 6 is a composite number.
b) 5
- Factors of 5: 1, 5
- 5 can only be divided evenly by 1 and 5.
- Therefore, 5 is not a composite number.
c) 7
- Factors of 7: 1, 7
- 7 can only be divided evenly by 1 and 7.
- Therefore, 7 is not a composite number.
d) 3
- Factors of 3: 1, 3
- 3 can only be divided evenly by 1 and 3.
- Therefore, 3 is not a composite number.
Among the given options, only option 'a' (6) is a composite number. It has more than two factors, namely 1, 2, 3, and 6. The other options, 5, 7, and 3, are prime numbers as they only have two factors - 1 and themselves.
Therefore, the correct answer is option 'A' - 6.
