factor tree
Find the factors of the number. If the only factors are 1 and itself, it is prime.A prime number is a positive integer with two factors: one and the number itself.A composite number is a positive integer with more than two factors.
One needs the composite number before he can find its factors. Thus the solution I shall give is ∞.
If it has more than two factors. If you find a third factor, you know.
A number is prime when it only has one and itself as factors is prime. Therefore, to tell if a number is prime or composite simply find it's factors. If it has more than two factors than it is not a prime number, it is composite.
A number is composite if it has more than two factors. Once you find a third, you know.
Composite numbers have more than two factors. Once you find a third factor, you know your number is composite.
Factor it. If you find more than two factors, it's composite.
A number is composite if it has more than two factors. Once you find a third, you're done.
To find a composite number, think of two numbers that can be multiplied to equal that number. For example, 15 is a composite number because its factors are 1, 3, 5 and 15. For a number to be composite, it should have more than two factors.To know 15 is a composite number, know:1 x 15=153 x 5 =15All composite numbers have more than two factors whereas prime numbers have only two factors.
prime numbers
4 is composite because 2x2=4 and when you are trying to find the factors of 4 you get 1,2,4.
By factoring them. Prime numbers have only two factors. Composite numbers have three or more.
