No. Numbers that are divisible by 2 must end in an even number (0,2,4,6,8)

All of them.

2 is not divisible by 345.

3 + 4 + 5 = 12 which is not divisible by 9, so 345 is not divisible by 9.

Itself because 345/345 = 1

345 is not divisible by 9. A quick rule for checking to see if a number is divisible by 9 is to add all of the number's digits. If their sum is divisible by 9, so is the number.2+3+4 = 9, which is divisible by 9, so 234 is divisible by 9. (234/9 = 16)3+4+5 = 123, which is not divisible by 9, so 345 is not divisible by 9 (345/9 = 38 r 3)5+6+7 = 18, which is divisible by 9, so 567 is divisible by 9 (567/9 = 63)

All multiples of 345, which is an infinite number.

345 is divisible by 2, but it results in 172.5, which is not an integer.

The even ones.

1, 3, 5, 15, 23, 69, 115, 345.

The rule of divisibility for 4 is if the last two numbers are divisible by 4, the whole number is as well. You can immediately disqualify odd numbers, since multiples of 4 have to be even. That qualifies 184, 92 and 5796.

Prime numbers are divisible because any numbers that are divisible are prime. If a number isn't divisible, it isn't prime. Prime numbers have to be divisible by at least one pair of numbers to be prime.

All numbers are divisible by 1.

Numbers are divisible by their factors. Multiples are divisible by their numbers.

The lists of numbers divisible by and not divisible by 600 are both infinite.

No, it is not divisible by 9. To check if a number is divisible by 9 add all the digits together and if this sum is divisible by 9, then so is the original number. As the check can be applied to the sum, keep adding the digits together until a single digit remains. If this digit is 9, then the original number is divisible by 9 (otherwise it gives the remainder when the original number is divided by 9). for 345: 3 + 4 +5 = 12 for 12: 1 + 2 = 3 which is not 9, so 345 is not divisible by 9. (The remainder when 345 is divided by 9 is 3.)
