Sunday Times Teaser 2950 – Ten Digits

by Andrew Skidmore

Published April 7 2019 (link)

Without repeating a digit I have written down three numbers, all greater than one.

Each number contains a different number of digits.

If I also write down the product of all three numbers, then the total number of digits I have used is ten.

The product contains two different digits, each twice, neither of which appear in the three original numbers.

What is the product?
