3 is Prime number so its only factors are 1 and itself. ^_^
Factors can be prime or composite. The factors of 30 are 1,2,3,5,6,10,15 and 30. Of these, 3 and 5 are prime. The rest are composite except for 1, which is neither.
69 is composite 1,69,3,23 are the factors.
3 is a prime number because it has only two factors which are itself and one. A composite number has factors other than 1 and itself.prime
Nine is composite. The factors of 9 are: 1 3 9
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.
771 is a composite number. Its prime factors are 3, 257
A prime number is 2 factors and a composite number is 3 or more!
15 is a composite number because it has more than two factors. Its factors are 1, 3, 5, and 15.15 is a composite number as it is divisible by 1, 3, 5 and 15.composite. 3*5=1515 is a composite number because it has more than 2 factors
The prime factors of 78 are 2, 3, and 13.
111 is composite. Its factors (besides 1 and 111) are 3 and 37.
21 is a Composite Number. A prime number is a whole number that only has two factors which are itself and one. A composite number has factors in addition to one and itself. 21 is divisible by 3 and 7.
ok well i am in prime and composite in math class and this is how: If the number is a prime then it can only have 2 factors. If it has 3 or more it is a composite number. Say 25 has a lot of factors so it is a composite number. And if 1 has only 1 factor then it is a prime number. And there you have prime and composite.
