The product of two number's is 1,000,000. No digit of either number is a zero. What are the number's?

Hint: Find the prime factorization of 1,000,000. Then figure out a way to multiply those factors that will give you numbers with no zeroes. (Note: Any product of 2 and 5 will result in a zero in the ones place.)

1,000,000/2 = 500,000
your 2 numbers are----> 2, 500000
Sorry, No digit can be a 0.Originally Posted by Sir_Loo
Since one number must end with 5, and the other with 2 or 4 or 6 or 8,
then the product of 1000000 will be from (10x + 5)(10y + 2 or 4 or 6 or 8),
where x and y = any integer > 0

I'm just an imagination of your figment !
That's good one, Denis. There are a lot of jokes about statistics.
As far as the problem goes, I was thinking why not the prime factorization of 1000000. That's what Stapel suggested, too.

No 0's.

I coded a program that figured it out in under a second, talk about efficiency eh?
