With 123 digits you can make 123 one-digit numbers.
There is no pair of prime numbers that sum to 123.Proof :Any two odd primes will sum to an even number, thus excluding 123 which is odd.Since 2 is the only even prime, the only possible solution is 2 + 121 = 123.But, 121 is not prime because it is 11 x 11.A similar proof shows that there is no pair of primes whose difference is 123.There are two primes that multiply to 123 : - 3 and 41.
If you meant what whole numbers can you use to multiply to 18, there's 9x2, 6x3, and of course 1x18 but you could multiply any number[s] to 18
