Forming three three digit numbers that use the numbers 1-9 without repeating, the highest product possible is 611,721,516. This is formed from the numbers 941, 852, and 763.

There are only two prime numbers that are consecutive numbers, 2 and 3. Their product is 2 x 3 = 6. The first prime numbers are 2, 3, 5, and 7 and the only two consecutive prime numbers whose product is a single digit are 2 and 3. (The next two consecutive prime numbers, 3 and 5, have a two-digit product.)

Its 28 and 29.
The answer is vague but correct . Take any two prime numbers whose combined digit length is 501 and their product will generate a 500 or a 501 digit number.

Numbers whose product is one is called multiplicative inverses.
Ten.
two prime numbers whose product is 141 = 3 & 47
3 and 7 are prime numbers whose product is 21.
