Prime Numbers
A prime number is a number that has exactly two factors: 1 and itself. All whole numbers greater than 1 are either prime numbers or can be written as the product of prime numbers. There are an infinite number of prime numbers, but they occur less frequently among larger numbers. Prime numbers are important in cryptography and number theory.

Composite relatively prime numbers mean?
Relatively prime numbers share no common factors other than 1.
Which numbers are prime and which are composite?
Prime numbers have two factors, composite numbers have more than two.
If the number has a remainder of 2 when divided by 5, it must end in either 2 or 7. Because adding 10 to a number ending in 2 will not be a prime number, it must end in 7. Because you will have a prime number if you subtract 10, it must be greater than 10. The possible numbers are:
17
27
37
47
The only one of these that is divisible by 3 is 27. If you subtract 10 from 27, you have 17, which is a prime number. If you add 10 to 27, you have 37, which is a prime number. The factors of 27 are 1, 3, 9, and 27, so it has only two factors other than 1 and itself. When divided by 5, the result is 5 remainder 2. Thus, 27 fits all the conditions.

Why is this Math problem2x2x2x5x5x9x11x15 not a correct prime factorization?
because 9 and 15 aren't prime numbers they can be divisible by 3 and 5 it has to be prime numbers only

What is the largest prime factor of 1250?
The prime factors of 1250 are 2 and 5. The highest prime factor is therefore 5.
Algorithm to find prime numbers below ten?
Take each number in turn, call it "n", and check whether it has any factors f, such that 1 < f < n. If it doesn't, it is a prime number.

In addition to ' 1 ' and itself, 18 has the additional factors 2, 3, 6, and 9,
so it's not prime.
Composite means it would have more than 1 and itself as factors, which it does; however, if it's prime, the only two factors are 1 and the number given.
