using digit 1,2,3,4 and 5 to form a 2digit and a 3 digit number so that the product is the least product possible. using each digit only once

Clearly the 3 digit number should start with 1 to be as small as possible
then the 2ditit should start with a 2
logical choices choices:
134 25  3350
135 24  3240
145 23  3335
looks like 135 and 24
