Question 773789
Great deal of information about these two numbers.  The solution will easily come from just these assignings and and equations:
m = lesser number
n = greater number
---- no concern about odd or even----
---- no concern about product of 3----


m+n=198 and n=5m  based on the other parts of the description.
Substitution of n,
m+5m=198
6m=198
m=33
Use the value in n=5m,
n=165


------------------------------------------
SUMMARY: {{{highlight(m=33)}}} and {{{highlight(n=165)}}}
Both of these are multiples of 3, and 165=5*33
Both numbers are odd.
