The HCF is the largest number that both numbers can be divided by. If the HCF is 1, that would suggest that the two numbers share no prime factors. Thus, any two numbers which are coprime will have an HCF of 1. Consecutive numbers are good examples here - 15 and 16, 27 and 28, 104 and 105, all have an HCF of 1.
220 = 2 x 110 or 4 x 55 or 5 x 44 or 10 x 22 or 11 x 20. None of these have 15 as a factor, so the answer to your question is: no.
As a general rule, the product of the GCF and the LCM is equal to the product of the original numbers. That would make the answer to this problem 6240. Unfortunately, the GCF of 348 and 6240 isn't 87 and their LCM isn't 24960. Someone notated this problem incorrectly.
The highest common factor of the numbers 104, 348 and 220 is 4.
The highest common multiple of any set of integers is infinite.

84 : 104 = 21 : 26 (simplifying by dividing both sides of the ration by the hcf(84, 104) = 4)
The GCF is 13.
To find the LCM of 110 and 20, you first need to break them up into their prime factors: 110 = 2x5x11 20 = 2x2x5 The next step is to identify the HCF. In this case the HCF will be 2x5 = 10. To find the LCM you multiply the numbers together and divide by the HCF: 110x20/10 = 220. Thus the LCM of 110 and 20 is 220.

104 = 2*2*2*2*13 and 75 = 3*5*5 so hcf = 1
