Well, if 10*10*10 = 1000, can you think of 3 prime numbers each in the ballpark of 10?

1001 is not divisible by 3
Since there is no divisibility test for 7, try dividing by 7

3 and 5 don't work, check 7

actually there is an easy trick to see that this is divisible by 11
start with the last digit, then compute as follows:
\[1-0+0-1=0\] so the remainder when dividing by 11 is 0, i.e. it is divisible by 11

Alternatively, look at the list of the first 10 primes: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29
Pick the three closest to 10, multiply them together and make sure the product is 1001.
