f is a one-to-one function from the set of positive integers to itself such that f(xy) = f(x) × f(y). Find the minimum possible value of f(2020).

f একটি এক-এক ফাংশন, যার ডোমেইন ও কো-ডোমেইন উভয়ই ধনাত্মক পূর্ণসংখ্যার সেট এবং f(xy) = f(x) × f(y)। f(2020)-এর সম্ভাব্য সর্বনিম্ন মান বের কর।

The Mathematician does not study math because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.
