Please add the following testcase:

869637034218881024 = 2^18 * 1806487 * 1836383

The answer should be "Yes". My solution prints "No" and nevertheless has AC.

Thank you! Good test.
I found another good one. 999979520100663296. I think it's stronger.
However I got AC before, but i was looking for a good test.

One of the largest allowed numbers
999999999987679232 = 2^19 * 1907348632789
where the second multiplier is a prime number.
