The way to know the Prime Numbers is to find out if they can only Multiplied Once ,The way to know Composite Numbers is to find out if they can be Multiplied Twice
The same way as with smaller numbers, it may take longer. Just keep dividing by prime numbers until all the factors are prime.
'25' is odd, all right, but not prime. (It can be divided by 1, 5, and 25) By the way, prime numbers must be odd numbers. All even numbers can be divided by 2, at least, and are therefore not prime.
There is no simple way. The difficulty wit prime numbers is that there is no pattern.

Composite numbers are positive integers greater than 1 that have factors other than 1 and themselves. To find all the composite numbers between 1000 and 3000, we can start by listing the prime numbers in that range: 1009, 1013, 1019, 1021, 1031, 1033, and so on. Then, we can identify the numbers that are not prime, which are composite. This process would yield a list of composite numbers between 1000 and 3000.

No, there is no single definitative equaltion that will predict all prime numbers between 1 and 1000, while not including some composite numbers. However, there are many "rules of thumb" that can greatly increase the efficiency of an algorithm to find the primes. For example, all prime numbers greater than 6 are either one more or one less than a multiple of six. This combined with the 11 primes less than the square root of 1000, makes the algorithm 8 times as effective as a brute force approach.

it is a way of finding out all of the prime numbers that you have to multiply to equal the desired number.
Long way: find the smallest prime numbers and use a calculator. Short way: recognize that 2 and 5 are both prime. Multiply them to get 10. We know that every multiple of ten has a 0 in the units place, so the answer to your question is 0.
A prime number is one that is only divisible by 1 and itself. Just work out if it divides into anything. To do this try dividing the number by all prime numbers under its half way value.

Prime numbers are multiplied together in the same way as any integers may be multiplied together.
