    Answer:

    • 100 is divisible by 2, 4, 5, or 10
    • 435 is divisible by 3 or 5
    • 535 is divisible by 5

    Step-by-step explanation:

    A number is divisible by 2 if its units digit is even. {0, 2, 4, 6, 8}

    “Casting out 9s” is the process of summing digits, repeatedly, until a number 9 or less is obtained. For 435, that process results in …

      4 + 3 + 5 = 12; 1 + 2 = 3

    A number is divisible by 3 if the result of casting out 9s is divisible by 3. {3, 6, 9}

    A number is divisible by 4 if its last two digits are divisible by 4.

    A number is divisible by 5 if it ends in 0 or 5, and is divisible by 10 if it ends in 0.

    A number is divisible by 6 if it is both even and divisible by 3.

    __

    The number 100 is divisible by 2, 4, 5, and 10.

    The number 435 has a sum of digits of 3, so is divisible by 3 and 5.

    The sum of these numbers, the total number of members of Congress, 535, is divisible by 5 only.

    _____

    The other factor of 435 is 29, a prime; the other factor of 535 is 107, a prime.
