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.
The prime factors of a squared number are the prime factors, if any, of its square root.
Prime factorization is when you find all the prime factors of a number.
A prime number is any number that only has one and itself as factors. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
A prime number is any number that only has one and itself as factors. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
Any number that only has one and itself as factors is prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
The prime factors of a squared number are the prime factors, if any, of its square root.
Any prime number has two factors: 1 and the number itself.
A number is prime when it only has one and itself as factors is prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
The prime factors of 24 are 2 and 3.
Once all the prime factors of a number have been found, the number of factors the number has and what they are can be found. I'd be finding the prime factors first before finding all the factors of a number, so I'd rather find all the prime factors as it means I can stop before I have to do more work in finding all the factors.

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.
Five has no even factors and is therefore a prime number. 5 is a prime number. Its only factors are one and itself.
