To find the LCM, you multiply the numbers together and then divide by the HCF. In this case, we don't know the numbers, but we have the HCF (13) and we have the product of the numbers (1690). Thus all you do is divide 1690 by 13 to get:

1690/13 = 130

And thus the LCM of two numbers whose hcf is 13 and product is 1690 is 130.
