Expressing a number as a "product of its prime factors" is also known as the prime factorization. To find the prime factorization, keep dividing a number by prime numbers until all the factors are prime. You can also use a factor tree or rainbow or fireworks or whichever method works best for you. Example: 330 330 165,2 55,3,2 11,5,3,2 2 x 3 x 5 x 11 = 330, expressed as a product of its prime factors.
