Prime and Composite Numbers
rectangle Problem 1: The area of a rectangular garden is 7 square yards. List all possible whole-number dimensions the garden can have.
Solution: 1 yd x 7 yd
The whole-number dimensions, 1 and 7, of the rectangular garden above, are the factors of the number 7.
Problem 2: The area of a rectangular garden is 8 square yards. List all possible whole-number dimensions the garden can have.
rectangle rectangle
Solution: 1 yd x 8 yd, 2 yd x 4 yd
The whole-number dimensions, 1, 2, 4 and 8, of the rectangular gardens in Problem 2, are the factors of the number 8. In Problem 1, the number 7 has only two factors. The number 7 is prime. In problem 2 above, the number 8 has four factors. The number 8 is composite.
Definitions
A prime number has only two factors: 1 and itself.
A composite number has more than two factors.
The number 1 is neither prime nor composite.
When the area of a rectangle is a prime number, there is only one set of possible dimensions for that rectangle. When the area of a rectangle is a composite number, there are two or more sets of possible dimensions for that rectangle. Each set of dimensions is a pair of factors.
To determine if a number is prime or composite, follow these steps:
Find all factors of the number.
If the number has only two factors, 1 and itself, then it is prime.
If the number has more than two factors, then it is composite.
Answer:
A prime no. is a whole number that has only two factors which are itself and one.
A composite number has factors in addition to one and itself.
