How to find proper aspect ratio

use following code to find aspect ration from source size and destination size.

private int[] getVideoSizeWithAspect(int srcWidth, int srcHeight, int destWidth, int destHeight) {
        int aspectWidthByDestWidth, aspectHeightByDestWidth;
        int aspectWidthByDestHeight, aspectHeightByDestHeight;

        /* aspect sizes related to width */
        aspectWidthByDestWidth = destWidth;
        aspectHeightByDestWidth = aspectWidthByDestWidth * srcHeight / srcWidth;

        /* aspect sizes related to height */
        aspectHeightByDestHeight = destHeight;
        aspectWidthByDestHeight = aspectHeightByDestHeight * srcWidth / srcHeight;

        if (aspectWidthByDestWidth > aspectWidthByDestHeight && aspectHeightByDestWidth <= destHeight) {
            int[] videoViewSize = new int[2];
            videoViewSize[0] = aspectWidthByDestWidth;
            videoViewSize[1] = aspectHeightByDestWidth;
            return videoViewSize;
        } else {
            int[] videoViewSize = new int[2];
            videoViewSize[0] = aspectWidthByDestHeight;
            videoViewSize[1] = aspectHeightByDestHeight;
            return videoViewSize;
        }
    }
