Problem #188

• If N = 1000000, how many positive integers less than or equal to N are divisible by 2, 3, 4, 5, 6, 7, 8, 9, or 10? [Note: As usual, "or" is not exclusive; for example 10 and 12 are both divisible by 2 or by 3.]
• As N becomes arbitrarily large, what fraction of positive integers less than or equal to N are divisible by 2, 3, 4, 5, 6, 7, 8, 9, or 10?

The solution will be posted shortly.
