How can you determine whether a counting number is a composite number?

Start looking for factors; you already know that 1 is a factor, and that the number itself is a second factor (unless the number is 1). As soon as you find a factor that is neither 1 nor the number itself, the number is composite. If you find exactly two factors, the number is prime. If the number has only one factor, the number is 1, which is neither prime nor composite.

How to get largest prime factor?

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 largest of those numbers is the largest prime factor.

Can you give you some prime number answers like 127 what two factors does it haveand like these what two factors do these have157 131?

Every prime number has exactly two factors. One of the factors is ' 1 '.The other factor is the number itself. If the number has any more factors,then it's not a prime number.If someone gives you a number, guarantees that it's definitely a prime number,and asks you to find the factors, you know the answer immediately. There aretwo factors. One of the factors is ' 1 ', the other factor is the number itself, andthere are no more factors.
