  1. Rather than being divisible by various numbers, what if there is a remainder?

    For example:

    Suppose you divide a number by 2 and the remainder is 1.
    Suppose, further, that when you divide this number by 3, 4, 5, 6, and 7, the remainder in each case is 1.

    What is the smallest positive number that satisfies the constraints above?

    For example:

    Suppose you divide a number by 2 and the remainder is q.

  3. as the problem is stated, i don’t think there is an answer.

    .001 is divisible by all the numbers 1, through 10, as is .0001, and .00001.

    it is not *wholly* divisible by any of the numbers; however, this is not a condition in the problem setup.
