SUMMARY

The discussion clarifies the distinctions between odd, composite, and prime numbers. An odd number is defined as an integer not divisible by 2, with 3 serving as an example. A composite number, such as 12, is a whole number that has factors other than 1 and itself. In contrast, a prime number is a natural number greater than 1 that has no divisors other than 1 and itself, exemplified by the number 17.

An odd number is an integer not divisible by 2. 3 is an odd number because 3/2 is not an integer.

A composite number is a whole number that has factors other than 1 and itself. 12 is a composite number because it has the factors 1, 2, 3, 4, 6, 12.

A prime number is a natural number greater than 1 that has no factors other than 1 and itself. 17 is a prime number by definition.

Good information for review.
