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.

(30, 3150), (90,1050), (150, 630) and (210, 450).
The product of the GCF and LCM of two numbers is equal to the product of the two numbers. The other number is 126.
HCF is the highest common factor of two or more numbers. HCf of 260 and 560 is 20.
if the product of two numbers is 810 if there hcf is 9 find Lcm

They are 39 and 52.
The LCM of two numbers is their product if and only if the two numbers are co prime, that is their HCF is 1. Otherwise their LCM in not their product, in fact, it is their product divided by their HCF.
The GCF is 36.
Divide the product of the original numbers by 108, the LCM. The result will be the GCF.
(30, 3150), (90,1050), (150, 630) and (210, 450).
LCM = product/HCF so product = LCM/HCF in this case 380/16 which is 23.75, so the answer to your question is no.
Yes.
Yes.
At least 2 or more numbers are needed to find their hcf but 66 as a product of its prime factors is: 2*3*11 = 66
