From the wikipedia reference page: "Subtract the quantity of the digits 2, 5, and 8 in the number from the quantity of the digits 1, 4, and 7 in the number. 65 is not a prime number. 3: The next trick is to add all the digits of the number, and see whether the result is divisible by 3. To illustrate this procedure let us find the binary equivalent of number 108. Arrange the digits 0 to 9 such that the number formed by the first digit is divisible by 1, the number formed by the first two digits is divisible by 2, that formed by the first three digits divisible by 3, and so forth; thus the number formed by the first 9 digits will be divisible by 9 and that formed by all 10 digits divisible by 10. In the second example, 3 does not go into ten evenly. Some are: Multiply each digit in the candidate number (from right to left) by the digit in the corresponding position in this pattern: 1, 3, 2, -1, -3, -2 (1 applies to the ones digit, 3 to the tens digit, etc. Unsigned binary numbers do not have sign bit, whereas signed binary numbers uses signed bit as well or these can be distinguishable between positive and negative numbers. Hints: In case of input data being supplied to the. com - all you need to know about numbers. Construct a "divisible-by-3" FSM that accepts a binary number entered one bit at a time, most significant bit first, and indicates with a light if the number entered so far is divisible 6. Solution: The language L3 accepts precisely those binary strings which when interpreted as numbers are exactly divisible by 3. The argument should already be RLE-coded, and have a length divisible by 3 (except possibly the last fragment). File:Binary and generalized Fibonacci numbers - runlength divisible by 3 (Tribonacci numbers). It is divisible by 5.
