magic primes

I call 7,11,13
as magic primes because by multiplying them we will get a magic number........... if you multiply any three digit number with these three primes consecutively produces a number which has six digits and formed by placing this three digit number adjacent.
for example........... let xyz be our three digit number by multiplying it with 7,11,13 we will get a number xyzxyz.
the magic number is 1001.
even though it looks simpler application part is good.
