What is 60 as a product of prime?
Solution: Since, the prime factors of 60 are 2, 3, 5. Therefore, the product of prime factors = 2 × 3 × 5 = 30.
What is the prime factor of 12?
The numbers 2 and 3 are the only prime factors of 12, but a prime factorization of 12 must list the 2 twice — 2 × 2 × 3 (or 22 × 3), because 2 × 3, by itself, doesn’t make 12. Though many numbers can be factored in more than one way, their prime factorization is unique!
