A factor tree is one way of notating the process of finding the prime factorization of a given number.
210
105,2
35,3,2
7,5,3,2
2 x 3 x 5 x 7 = 210
it means to find out if the number is composite or prime
Find the prime factorization. Identify the distinct prime factors. Add them up.
Find the prime factors for 99. Any other prime number is not a prime factor. There are an infinite number of answers, since the set of prime numbers if infinite.
To find the highest prime factor of 420, we first need to factorize 420 into its prime factors. 420 can be expressed as 2^2 * 3 * 5 * 7. The highest prime factor is 7. Prime factors are numbers that can only be divided by 1 and themselves without leaving a remainder, and the highest prime factor is the largest prime number that can divide the original number.
All numbers that only have one and itself as factors are prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
3 could be a prime factor but it depends on which number you're trying to find the prime factors of.

73 is a prime number. A prime number has only two factors, one and the number itself.
13 is a prime number. A prime number only has two factors: one and itself.

Factor 756 into prime factors. Then add additional prime factors, such that each prime factor occurs a number of times that is a multiple of 3. The product of the additional prime factors is "k".
To find the prime factors of a number, start with any factor pair for the number and keep factoring until all factors are prime. 26 2 x 13 Both factors are prime, so 2 and 13 are the prime factors of 26.
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.
Factor it. If it has only two factors, it's prime. If it has more than two, it's composite.
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.
To find the highest prime factor of 420, we first need to factorize 420 into its prime factors. 420 can be expressed as 2^2 * 3 * 5 * 7. The highest prime factor is 7. Prime factors are numbers that can only be divided by 1 and themselves without leaving a remainder, and the highest prime factor is the largest prime number that can divide the original number.
