no multiple of 5 has a 4 in the ones place!

So 2 is the required factor.

The only possible options for the factors are 2 and 5 since multiplying any other numbers by 0 or 10 will not yield a product with a 4 in the ones place. Therefore, one of the factors must be either 2 or 5.

Apologies for the mistake. You are correct, none of the multiples of 5 will have a 4 in the ones place, so the required factor must be 2.
