Best Answer

You cannot.

The numbers 2 and 12 have hcf = 2 and LCM = 12

The numbers 4 and 6 also have hcf = 2 and LCM = 12

So if you just knew the hcf and LCM you would not know which of the two was the required pair.

Q: How do you find sets of two numbers if HCF and LCM are known?

You need at least two numbers to find a GCF.

First you will need to pick out the two numbers. Then you can use your textbook and the instructions in order to draw out the flow chart.

It is not possible to give a sensible answer to this question. The highest common factor (HCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!

The HCF is 24, so both numbers will have 24 as a factor. This means both will be multiples of 24 so we can simply divide 144 by 24 to find which multiple. Do this and you get: 144/24 = 6 So the number multiple of 24 each number is needs to add up to 6. However, it cannot be 3 and 3 or 2 and 4 as then the numbers would have a greater HCF. Thus it must be 5x24 and 1x24, or 24 and 120.

its not possible with only one number. you need two numbers.

HCF is the highest common factor of two or more numbers. HCf of 260 and 560 is 20.

The GCF is 70.

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.
