9. write the factors of each number. then, write if it is prime or composite 81 - 33- 28 -​


Answer:

Yes, since 81 has more than two factors i.e. 1, 3, 9, 27, 81. In other words, 81 is a composite number because 81 has more than 2 factors.Yes, since 33 has more than two factors i.e. 1, 3, 11, 33. In other words, 33 is a composite number because 33 has more than 2 factors."No, 28 is not a prime number." Since 28 has more than 2 factors i.e. 1, 2, 4, 7, 14, 28, it is a composite number.

What is Prime number ?

A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number.

What is composite number ?

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.

Example of (PM) :

The first Prime number.

2, 3, 5, 7, 11 etc. than 1 that is not a product of two smaller natural numbers.

Example of (CM) :

4, 6, 8, 9, 10 etc. that has at least one divisor other than 1 and itself.
