Question

Find a number that has exactly 7 different prime factors. Explain how you found it.

Answer 1

The first seven prime numbers are 2, 3, 5, 7, 11, 13, 17
If you multiply all those numbers together, you'll have a product with 7 different prime factors (each of the numbers you multiplied).
So, 2 x 3 x 5 x 7 x 11 x 13 x 17 = 510,510
