What is the mystery number sentence?

Its factors are divisible by 3.
Its factors are divisible by 10.
Its product is greater than 2500.
Its product is less than 3000.

To find the mystery number sentence, we need to identify a number that satisfies all the given conditions.

First, let's think about numbers whose factors are divisible by 3 and 10. The first number that comes to mind is 30 because its factors (1, 2, 3, 5, 6, 10, 15, and 30) are all divisible by both 3 and 10.

Next, we consider the condition that the product of the factors is greater than 2500 and less than 3000. We can calculate the product of the factors of 30 by multiplying them together: 1 x 2 x 3 x 5 x 6 x 10 x 15 x 30 = 270,000. Since 270,000 is greater than 2500 and less than 3000, the mystery number sentence is satisfied by the number 30.

Therefore, the mystery number sentence is 30.
