Today we learn about how to get min price and max price from product collection. First, you have to get a collection of the product. Then their two predefined functions for getting min price getMinPrice and get max price getMaxPrice

Now we implement the code for getting min price and max price.

protected $_productCollectionFactory;

public function __construct(
        \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productFactory
    ) {
        $this->_productCollectionFactory = $productFactory;
    }

public function getProductCollection()
    {
      $productCollection = $this->_productCollectionFactory->create();
      $maxPrice = $productCollection>getMaxPrice();
     $minPrice = $productCollection>getMinPrice();
    }

}
