Using digits 0-9 find 5 numbers that are multiples of 3?
Any number using each of the digits once will be a multiple of 3: eg 1597864302
Maximum number that can be formed using all the digits 6 4 8 1 without repetition and which is divisible by 9?
The biggest number that can be formed with just those four digits once each, is 8641 - however - no number made from those digits can be divided by 9 because in order for a number to be exactly divisible by nine - the sum of the digits must also divide exactly by nine. The sum of the digits 6, 4 8 & 1 is 19 !Another Answer:-The above answer is absolutely correct.A possible solution is 61+8/4 = 63 and 7*9 = 63

The factor of every palindrome with an even number of digits?
Every palindrome with an even number of digits is divisible by 11. The easiest way to see this is to recall the divisibility rule by 11: if a number X is written as ABCDEFG... (here A,B,C, ... are digits), then it's divisible by 11 if and only if the sum A-B+C-D+E-F+G-... is divisible by 11. In a palindrome with an even number of digits, each digit will appear in an odd position and in an even position, so when we calculate this sum, it will be added once and subtracted once, canceling. Since all the digits cancel, the sum A-B+C-D+... will be 0, which is divisible by 11. So the original number ABCD....DCBA was also divisible by 11.
