Product of the first three primes

Answer:

THIRTY

Hint:

Think of the smallest numbers that can only be divided by one and themselves, then multiply them together to find a round number.

Explanation:

The first three prime numbers are 2, 3, and 5. Multiply them together (2 × 3 × 5) and you get 30, which is written out as "thirty." The clue plays on the mathematical definition of "product," meaning the result of multiplication, rather than something you buy.
