Answer:

957,697,598

Explanation:

You want a number that has 7 different prime factors.

Primes

If we choose 7 primes at random from the first 20, we might have the list ...

{2, 11, 13, 23, 41, 53, 67}

The product of these primes will have 7 different prime factors.

2 × 11 × 13 × 23 × 41 × 53 × 67 = 957,697,598

The number 957,697,598 has exactly 7 different prime factors.

Additional comment

Any of these factors might have a power greater than 1 without changing the number of different primes. We chose to keep it simple.

The second attachment shows the first 20 prime numbers.
