No, they are composite numbers. The factors of 15 are 1, 3, 5, and 15. The factors of 33 are 1, 3, 11, and 33. Prime numbers have two factors: 1 and the number itself, so 15 and 33 cannot be prime.

Factors are numbers that, when multiplied together, equal a number. For example, the factors of 6 are 1, 2, and 3. When these numbers (1, 2, 3) are multiplied together, they equal 6.

Yes. Composite numbers have more than exactly two factors; 39 has four factors: 1, 3, 13, 39. Prime numbers have exactly two factors, eg 3 has the two factors 1 and 3. Square numbers have an odd number of factors, eg 36 has nine factors: 1, 2, 3, 4, 6, 9, 12, 18, 36. The number 1 is not prime as it only has one factor: 1.

Prime numbers have exactly two factors. 3 has exactly two factors: 1 and 3. So 3 is prime. Composite numbers have more than two factors. 4 is composite because it has three factors: 1, 2, and 4.

No, they are factors of 15. Factors go into numbers, numbers go into multiples.
