Odd numbers – Meanwhile odd numbers are the opposite of even numbers. Odd numbers are numbers that cannot be divided evenly into groups of two. To determine if a number is an odd number, we look at the numbers in the ones place and if they end in – 1, 3, 5, 7 or 9, they are odd numbers.
Prime numbers – This is where it begins to get a little tricky. A prime number is a whole number greater than 1 that cannot be made by multiplying other whole numbers. In other words, its factors are one and the number itself. Further, a prime number can be divided without a remainder only by itself and by 1.
Composite numbers – A composite number is a positive integer (whole, not fractional number) that can be formed by multiplying two smaller positive integers.
