:

$productId = 100;
$product = Mage::getModel('catalog/product')->load($productId);
if ($product->getId()) {
        $categoryIds = $product->getCategoryIds();
        if (is_array($categoryIds) and count($categoryIds) >= 1) {
            $cat = Mage::getModel('catalog/category')->load($categoryIds[0]);
			echo $cat->getId()."<br>";
        }else{
        echo "No Category Found.";
       }
