Question

Which of the following is a Composite number?
A) 0
B) 19
C) 29
D) 91

Answer 1

Answer:

D) 91

Step-by-step explanation:

What are composite numbers? Composite numbers are those numbers which have more than 2 factors.

Since 0 is neither a prime nor a composite number, it is not the answer.

19 has only two factors, ie, 1 and 19 itself.

29 also has only two factors, ie, 1 and 29 itself.

91 is a composite number because it has more than two factors, ie, 1 and 19 (1*19 = 19) and, 7 and 13 (7*13 = 19).

Hope it helps.
