 Traveller's Woe (Posted on 2013-11-05)
An unknown route with a MAP invites an INROAD from many an IMP.

Now MAP * IMP = INROAD if the following conditions are met:
1. The two multipliers are semiprimes.
2. Each of the 4-digit partial products are a pair of consecutive integers with a difference equal to their multiplying digit.

Determine the 4 primes which form the original multipliers.

Bonus Challenge:
The alphametic does have two solutions but the second does not meet the given criteria. Identify why.

 Submitted by brianjn No Rating Solution: (Hide) In the first instance: 807 * 287 = 231609 807 is the product of 269 and 3. 287 is the product of 41 and 7. Bonus: The product is formed from 3 primes, 857, 11 and 7: 857 187 160259
