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.
2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.
Small words make a difference. No prime number "has" a factor of 16. But 2 is the only prime number that "is" a factor of 16.
A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies
Not a lot. They're both prime numbers. A factor that is prime is used to make other numbers.
7 is a prime number; its only prime factor is 7.
No. 10 is not a prime number, which means it cannot be a prime factor. It can be a factor, but not a prime factor.
Itself because 2 is a prime number
7 is a Prime number; its only prime factor is 7.
13 is a prime number. It doesn't have a tree because its only prime factor is itself.
You don't. 41 is a prime number. Prime numbers don't have factor trees, since they only have one prime factor.
13 is a prime number. The only prime factor of a prime number is the number itself.
what number is not a prime factor
That's a prime factor.
