No. If you multiply any numbers, those numbers are factors of whatever product you get. Therefore, this product is a composite number; it has atleast the two factors you multiplyed before. Compposite numbers are never prime.
If the two factors above were prime, you would still end up with a composite number.
For example: 3 times 5 equals 15. The factors of 15 are 1, 3, 5, and 15. 15 is composite.
7 time 51 equals 357. The factors of 357 are 1, 7, 51, and 357. 357 is composite.
