Question 694313
Without more context, my guess as to the meaning of {{{k}}} and {{{m}}} is almost a wild guess.
For divisibility and prime factoring, I would use {{{k}}} and {{{m}}} to mean whole numbers.
Then, I would represent even numbers (multiples of 2) as {{{2k}}}, odd numbers as {{{2k+1}}}, and multiples of 3 as {{{3m}}}.
The meaning of your {{{k}}} and {{{m}}} has to have been defined at some point (maybe a couple of pages/lessons back).
