Hi David,

If a<=b, then one can take
k=!b such that the question is solved 
in affirmative.

Best regards,

Subject: [seqfan] Number theory question

Let !n = 0! + 1! + ... + n! = A003422(n)

For integer k, is it true that

        !a == k (mod a)


        !b == k (mod b)

together imply

        !c == k (mod c)


        c = lcm(a, b)
