I have difficulty in understanding what you are saying, and also in interpreting what the rest are saying. My answer would also greatly differ from theirs, and part of that is that your question is not clear. For clarity, can you explain what you are asking for? How many of the \(a, b, c\) terms are you allowed? Just 3, or any finite number? Are the positive integers given? I also believe that you are missing the condition that \(a, b, c \) are non-negative numbers.

For example, if \(a+b+c = k\), then the maximum value of \( a^4 b^2 c^2 \) is actually infinity (without the condition of non-negative numbers). With that condition, a possible value is \( k^4 \) (with \(a=k, b=0, c=0\)), which differs from what Raja and Pratik are saying. (I'm not saying that this is the maximum possible, but you can also track and see where they are going wrong.)

THEN YOU HAVE TO KNOW A LITTLE ABOUT THE INEQUALITIES………I THINK I COULD SATISFY YOU……
Let a,b,c…. any positive real numbers whose sum a+b+c+….=given positive integer or a constant….
Since m,n,p,…..are constants (a^m)(b^n)(c^p)…..will be greatest when
(a/m)^m(b/n)^n(c/p)^p…..[let’s take this product as numbered (1)] is greatest.
The product (1) consists of m factors each equal to (a/m),n factors each equal to (b/n),p factors each equal to (c/p),and so on….. the sum of all these factors is equal to
m(a/m)+n(b/n)+p(c/p)+…….=a+b+c+…..=constant(given)….
Therefore the product (1) is greatest when all these factors are equal to one another i.e. when
a/m=b/n=c/p=…….= [(a+b+c+…..)/(m+n+p+….)]
so the greatest value of the product (1) is
=(m^m)(n^n)(p^p)…… { [ (a+b+c+…..)/(m+n+p+……)]^(m+n+p+……)}
HOPE THIS HELPS…..

if a, b, c are positive no's then you can apply AM-GM inequality and note that product of any no of nos is maximum when all the no's are equal. So if, you have to maximize the product, in this case \( a^{m} =b^{n}=c^{p}\) and so on.

Are a,b,c positive integers or they can be any no's??
