Why is it not possible for 123111970 to be a prime number?
Because it has more than two factors
Are there prime numbers that are also square mumbers?
No. That isn't possible: A prime number, by definition, has no smaller factors. A square number does have a smaller factor - the number that is squared.
What is the difference between factors of a number and prime factors of a number?
All numbers have factors. Some factors are prime numbers. These are known as prime factors. The set of prime factors is a subset of the set of factors for any given number.

How can you determine if a number is prime by looking at the factors of the number?
A prime number only has two factors. If the number you're looking at has more than two factors, it is not prime.
How do you know when you have found the longest possible sting factors of a number?
All of the factors are prime.
Is it true that one is a factor of every prime number?
Yes, that is the definition of a prime number, having only two possible factors, one and the prime number itself.

What is the largest two digit number to the exactly 9 factors?
To have exactly 9 factors, the number would either have to have a prime number raised to the 8th. power; this is not possible with two digits.The other option is to have a prime number raised to the second power, times another prime number raised to the second power. (The number of factors in this case is (2 + 1)(2 + 1).) This is only possible if you use the prime factors 2 and 3; any other combination of prime numbers will yield a number that has more than 2 digits.
How many are prime number in the number system?
Any number that only has one and itself as factors is prime. Therefore, there is an infinite amount of prime numbers. Any number lower than 0 is not possible to be prime.
What strategy do you use to find factors?
Assuming you want all factors of a number: 1) Split a number into prime factors. 2) Combine the prime factors in all possible ways. To get the prime factors, you can systematically try out dividing the number by prime numbers, up to the number's square root (once the square of the prime number you try out is greater than the original number, you need not continue). For example, to find out prime factors of numbers up to 120, you only need to try dividing by 2, 3, 5, 7.
Are there prime numbers that are also square mumbers?
No. That isn't possible: A prime number, by definition, has no smaller factors. A square number does have a smaller factor - the number that is squared.
What are all the prime factors of 51 How does this help you find all the possible factors of the number?
The prime factors of 51 are 3 and 17. Once you add itself and one, you have all the factors. (1,3,17,51)
How do you know when you found the longest possible string of factors for a number?
When each one of them is a prime.
Which number less than 1000 has the most different prime factors?
210 has 4, which is the maximum possible. There are other numbers with 4 different prime factors.
What are the prime factors of a composite prime number?
There is not such a thing as a composite prime number. A prime number has exactly two factors. A composite number has more than two factors.
