Factors are numbers that can be multiplied together to make another number. For example, 3 and 12 are a factor pair of 36. Prime numbers are numbers that have exactly two factors, 1 and itself (i.e. 2, 3, 5, 7, 11,….). Then you continue to branch out until you only have prime factors left.
What are the two prime factors of 2000?

Can a positive number be factored into a prime?
Every positive number can be factored into a product of primes. For example, where 2, 3 and 5 are prime. The factorization of a number into only primes is called its prime factorization. Every number that is not itself prime has exactly one prime factorization.
What is the difference between factors and prime factors?
The PRIME factors are the factors that can’t be broken down any further, in this case, 2^2 * 5. So the PRIME factors are 2 and 5. The factors are ALL the various numbers that when multiplied together will give the given number. For instance, 20 = 2 * 10, or 4 * 5, or 20 * 1.
How is a prime number different from a composite number?
Therefore, a prime has only two factors, one and the number itself. For an example, 5 is a prime number since it is divisible only by one and the number itself. Positive integers that have more than two factors are termed as composite numbers. Eight is a composite number since it has more than two factors.
What are the divisors of a prime number?
So, prime number has no factors and it will have only two divisors. They are 1 and the number itself. If a number is not prime, then it is composite. If a number has more than two divisors, then it has factor or factors and it is composite.
