Hi, and welcome to the forum!
I am not sure what sigma ($\Sigma$ or $\sigma$) means in your problem. Perhaps you can use the formula editor to the right of the edit box to enter the formula exactly as it appears in the problem statement, as well as the complete problem statement itself. LaTeX symbol codes (they start with a backslash) should be enclosed in the $$...$$ tags.Vi Nguyen said:how to solve this problem

Hi Vi Nguyen! Welcome to MHB! ;)
The only sigma function I know, is the sum-of-divisors function. See https://en.m.wikipedia.org/wiki/Divisor_function .
In that case we have:
$$\sigma(210)=576$$
