Seeking guidance or recommendations (references) to determine the ratio analysis (for finance course) for Fiscal year 2017 and 2018 for Home Depot and Lowes. Key information i'm trying to locate are: current ratio, quick ratio, total asset turnover, average collection period, total debt of total assets, times interest earned, net profit margin, return on assets, return on equity, net profit margin, total asset turnover, equity multiplier, PE ratio, and market to book ratio.

Every resource I have found has different information, causing confusion on what the correct answers are, in order to compile the data and analyze it. Is there a correct place to go, to compile this information, without having to look at 20 different websites and everyone has different data? Thank you.
