36360 is a 5 digit number that is divisible by both 3 and 9.
There is no 5 digit number which is divisible by 23456910 (an 8-digit number)..
305 can only be [exactly] divided by 5 and not 2, 3, 6, 9 nor 10.Divisibility tests:2: NoNumber must be even (last digit divisible by 2). Last digit is 5 which is not even, so the whole number (305) not divisible by 2.3: NoAdd up the digits of the number; if this sum is divisible by 3, then the original number is divisible by 3: 3 + 0 + 5 = 8 which is not divisible by 3, so the original number (305) is not divisible by 3.5: YesLast digit is 0 or 5. Last digit is 5, so 305 is divisible by 5. 6: No6 = 2 x 3, so number must pass both tests for divisibility of 2 and 3; 305 fails tests for (both) 2 and 3 (above), so is not divisible by 6. 9: NoAdd up the digits of the number; if this sum is divisible by 9, then the original number is divisible by 9: 3 + 0 + 5 = 8 which is not divisible by 9, so the original number (305) is not divisible by 9.10: NoThe last digit of the number must be 0. Last digit is 5, so 305 is not divisible by 10.
A factor of a number is an integer that divides the number evenly (without remainder). So 2 and 3 are factors of 12 (12/2 is 6 and 12/3 is 4), but 7 is not a factor of 12 (12/7 is 1 remainder 5). 2 and 3 are not factors of 5 (notice 5 is prime).
A common factor refers to a factor that is COMMON to two or more numbers. You have only one number in the question! Any integer greater than 154590 is not a factor.
5 is not a factor of 9347. 5 is a factor of a number only if the last digit of the number is a 0 or a 5.

There are 5 numbers which can make the 3 digit numbers in this example. Therefore each digit in the 3 digit number has 5 choices of which number can be placed there. Therefore number of 3 digit numbers = 5 x 5 x 5 = 125
