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.

11 and 13
13 and 5 13+5=18 13x5=65
-13*-14 = 182

They are: 4 and -3
8 and 8
8 and 5
They are 2 and 140 because their LCM is 140 and their product is 280
