Prime numbers are easy. All prime numbers only have two factors, one and themselves. Composite numbers are trickier. Let's take 40 as an example. You know that 40 is divisible by
1 (because everything is)
2 (because it's even)
4 (because the last two digits are a multiple of 4)
5 (because the last digit is a 0)
Divide 40 by 1, 2, 4 and 5 and get 40, 20, 10 and 8 respectively. Arrange them in ascending order.
1, 2, 4, 5, 8, 10, 20, 40 are the factors of 40.

What relationship do prime and composite numbers have with factors?
Some factors are prime numbers, some are composite.
What is the prime factorization of a composite number?
A composite number has three or more factors. All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.Example: 210210 Divide by two.105,2 Divide by three.35,3,2 Divide by five.7,5,3,2 Stop. All the factors are prime.2 x 3 x 5 x 7 = 210That's the prime factorization of 210.
Can composite numbers be written as the product of prime factors?
Yes. Composite numbers can be written as the product of prime factors.
What is prime and composite numbers mean?
Prime numbers are numbers with only two factors. Composite numbers are numbers with more than two factors.
How are prime numbers and composite numbers related?
The relationship between prime numbers and composite numbers is that they are antonyms or opposites of each other. A natural number, is either prime or composite, but it can not be both. Prime numbers have only two factors, one and itself. Composite numbers are whole numbers that are not prime numbers, which means that they have factors other than one and itself.
Finding prime factors?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime.
What are the factors and prime factors of 601?
Only composite numbers have factors. 601 does not divide evenly by anything, therefore it is a prime number. Since it is a prime number its only factors are one and itself.
What numbers are prime numbers and what numbers are composite?
Prime numbers have two factors, composite numbers have more than two.
Which is prime and which is composite?
Prime numbers have two factors, composite numbers have more than two.
Which numbers are not composite numbers?
Composite numbers have more than two factors. So, the numbers which have two or less than two factors are not composite numbers. Numbers which have exactly two factors are prime numbers. 1 is an exceptional case because it is neither prime nor composite since it has only one factor which is 1.
How do you teach prime and composite numbers?
Prime numbers have two factors, composite numbers have more than two.
Why are some numbers prime and some numbers composite?
Prime numbers have only 2 factors while composite numbers have more than 2 factors
