Question from Alleyn

Can anyone help please? Question from Alleyn school....

Use digits 1-9 once only to fill the gaps. 4 digit blank number x 3 = 5 blank digit number.

So : - - - - x 3 = - - - - -

Is there some simple logic I'm missing? Trial and improvement is taking too long.

Many thanks

I think we might have had this before.

We know units of the left can't be 1 or we'd get another 3 in the answer, or a 5 as we'd get another 5.

What can we say about the Thousands if we get a five digit answer?

Does that help you get started?

I see someone already answered it previously... I will have a look at the thread. Should have done that first.
