Because when you divide 453 by 3, you get a whole number (a number that doesn't have a decimal or fraction) which comes out to be 151. However, when you divide 453 by 2, you get 226.5 or 226 1/2. Since this is not a whole number it is not divisible by 2. Anything divisible by 2 will end with and even number(2, 4, 6, 8, or 0(this does exclude 0 itself)) Divisibility does have rules to help
If the number is divisible by:
2 - it will end with an even number
3 - the sum of the digits will be a multiple of 3
4 - the last 2 digits will be a multiple of 4
5 - the number will end with a 5 or 0(excluding 0 again)
6 - the number is divisible by 2 and 3
7 - I haven't found any trick for 7 =( sorry
8 - the last 3 digits are divisible by 8
9 - the sum of the digits are a multiple of 9
10 - the number ends with 0(excluding 0)
Of course you could divide all of these on a calculator but here are some tricks to help.
Hope this helped =)
To get a number like this, it CANNOT be even. The number 453 is divisible by 3(goes into 453 ninenty one times), but not by 2.
Well, honey, anything that is a multiple of 453 is divisible by 453. So, if you find a number that can be evenly divided by 453 without leaving a remainder, then congratulations, you've got yourself a winner. Just remember, math doesn't have to be a drag, so go ahead and divide to your heart's content.
It is divisible by 6
102 is divisible by: 1 2 3 6 17 34 51 102.
For starters, the number 3 is divisible by 3 but not by 2. Next, 9, 27 etc. All the odd multiples of 3 are divisible by 3 but not 2. So there is an infinite number of numbers that are divisible by 3 and not 2.

Yes. The result is 151
Since 5232 is divisible by both 2 and 3, it is divisible by 6.A number must be divisible by both 2 and 3 to be divisible by 6.The number 5232 is even, so it is divisible by 2.If you add the individual digits in the number (5+2+3+2=12) you get a number that is divisible by 3, meaning the original number (5232) is also divisible by 3.
It is divisible by 6
Any number that is divisible by both 2 and 3 is divisible by 6.
Using the tests for divisibility:Divisible by 3:Add the digits and if the sum is divisible by 3, so is the original number: 2 + 3 + 4 = 9 which is divisible by 3, so 234 is divisible by 3Divisible by 6:Number is divisible by 2 and 3: Divisible by 2:If the number is even (last digit divisible by 2), then the whole number is divisible by 2. 234 is even so 234 is divisible by 2.Divisible by 3:Already shown above to be divisible by 3. 234 is divisible by both 2 & 3 so 234 is divisible by 6Divisible by 9:Add the digits and if the sum is divisible by 9, so is the original number: 2 + 3 + 4 = 9 which is divisible by 9, so 234 is divisible by 9Thus 234 is divisible by all 3, 6 & 9.
To determine if a number is divisible by 6, it must be divisible by both 2 and 3. To determine if a number is divisible by 2, it should be even - in other words, it should end with 0, 2, 4, 6, or 8. To determine if a number is divisible by 3, the sum of its digits should be divisible by 3. 54,132 is an even number, so it is divisible by 2. 5 + 4 + 1 + 3 + 2 = 15, which is divisible by 3, so 54,132 is divisible by 3. Since 54,132 is divisible by both 2 and 3, it is divisible by 6.
102 is divisible by: 1 2 3 6 17 34 51 102.
For starters, the number 3 is divisible by 3 but not by 2. Next, 9, 27 etc. All the odd multiples of 3 are divisible by 3 but not 2. So there is an infinite number of numbers that are divisible by 3 and not 2.
Rule: If it is divisible by 2 and by 3Numbers are divisible by 6 if they are divisible by 3 and 2. Therefore, for example, since 18 is divisible by 3 and 2, it is also divisible by 6.The divisibility rule for 6 is, it can go into the number if 2 and 3 can also.
