There is only one pair of whole numbers that satisfies both these conditions: their product is one million, and no digit of either number is a zero. What are the two numbers?

Answer:

64 and 15,625

One million = 10 to the sixth power
10 to the sixth = 2 to the sixth x 5 to the sixth
2 to the sixth = 64
5 to the sixth = 15,625
64 x 15,625 = 1,000,000
