1 is a composite number because 1 is not a product of 1.
2. To find the prime factorization of a number, divide it and all its factors until every remaining number is prime.
3. The result of multiplying a number by an number(not by a fraction).
Examples: • 12 is a multiple of 3, as 3 × 4 = 12 • 6 is a multiple of 3, as 3 × 2 = 6 • But 7 is NOT a multiple of 3
4. In math, a square number or perfect square is an number that is the square of an number; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3.
5.You get a square number by multiplying a number by itself, so knowing the square numbers is a handy way to remember part of the multiplication table. Although you probably remember without help that 2x2 = 4, you may be sketchy on some of the higher numbers, such as 7x7 = 49. Knowing the square numbers gives you another way to etch that multiplication table forever into your brain.. The following figure shows the first few square numbers: 1, 4, 9, 16, and 25.From here, you can determine more square numbers:36, 49 ,64 . . . .Visual aids can help you find square numbers. The tastiest visual aids you’ll ever find are those little square cheese-flavored crackers. (You probably have a box sitting somewhere in the pantry. If not, saltine crackers or any other square food works just as well.) Shake a bunch out of a box and place the little squares together to make bigger squares, as shown in the above figure.
