Question

3. Which is the smallest composite
number ? *
2
4
6
O
8

Answer 1

Correct option is

B

4

By definition of a composite number, It is a number that has other divisors besides 1 and the number itself. here,'1 ' is not a composite number because its divisor is one. and '2' is also not a composite number because it has only two divisors 1 and the number 2 itself but 4 is different. Its divisors are 1,2 and 4. So, this number satisfies the criterion of a composite number as stated above, Since besides 1, 2 is also a divisor of 4. So the answer is 4

Answer 2

Step-by-step explanation:

Composite numbers are all natural numbers that are not prime numbers since they can be divided by more than two numbers. The smallest composite number is 4. The smallest composite number of 2 digits is 10. 4 is a composite number because there are 2 variables.
