Prime numbers don't have factor trees. So if you can create a tree, your number's composite.
295 is composite - 5 x 59.
It is a prime.
Factor it. Prime numbers have two factors, composite numbers have more than two.
1 is neither a prime nor a composite number because it has only one factor (itself (1)). The definition of a prime number is a number that has the factor of one and itself, so one is not prime. The definition of a composite number is a number that has more than 2 factors, so one is not composite. One is a special number.
Factor them. Prime numbers have two factors, composite numbers have more than two.
295 is composite - 5 x 59.
A composite factor is a factor that is a composite number, as opposed to a prime factor which is a factor that is a prime number.
A composite factor is a factor that is a composite number, as opposed to a prime factor which is a factor that is a prime number.
It is another composite number.
Since 160 is a composite number, it would be a composite factor.
By looking at its factor patterns.
It is a prime.
It is a prime number.
12 is a composite number, not a prime factor.
A prime factor of a number is a prime number that evenly divides the number. A composite number is a number having more factors than just 1 and itself.
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.
No. The number 30 is composite and so it cannot be a prime factor.
