Here is a explanation of what Primes, Factors and Composites are.
Factor – A factor is a whole number that divides another whole number with no remainder
Prime – A prime number is a number with only 2 different factors: 1 and itself.
Composite – A composite number is a number that has 3 or more factors
(Factors are bold)
7 is a Prime number – 7÷7=1 7÷1=7
8 is a composite number – 8÷2=4 8÷4=2 8÷8=1 8÷1=8
Remember, if a number is a odd number it doesn’t mean it’s a prime number. For example 9, it is a composite number.
