Is A divisible by B?
means:
If I divide A by B, will there be a remainder?
Using only integers, if you divide 16,287 by 2, you will get 8143, with a remainder of 1. Therefore, 16287 is not divisible by 2.
Some numbers are easy to guess. A number is divisible by two only if its last digit is divisible by 2. The last digit in 16,287 is a 7. Not divisible by 2 (7 is an odd number).
16,287 is divisible by 3. If you divide it by three, you get 5429 with no remainder. Without doing the division, we can tell that it is by adding the value of all digits:
1+6+2+8+7 = 24
2+4=6
6 is divisible by 3
Therefore, 24 is divisible by 3 and
16,287 is divisible by 3.
A number is divisible by 5 only if it ends with a 5 or a 0.
16,287 is not divisible by 5.
16,287 divided by 5 = 3257, with a remainder of 2.
I skipped 4: for a number to be divisible by 4, it must be also divisible by 2 .
There are some tricks for higher numbers, but they are more complicated. Might as well just do the division and see if there is a remainder.
Is 16,287 divisible by 11?
Is the remainder 0 when you divide by 11?
(these are equivalent questions)

Not without a remainder...
To figure if a number is divisible by 2 evenly, check to see if the last digit is a 0, 2, 4, 6 or 8. If it is any of these, then it is evenly divisible. If not, it is not.

Your answer would be 8143.5 so no its not. The easiest way to tell is look at the last digit. Its an odd number; therefore, 16, 287 is an odd number so its not divisible by 2

Rule for divisibility by 2 is that the digit at units place is (number ends in) 0,2,4,6 or 8.
Now since 16,287 does not end in any of these therefore it is not divisible by 2

No, only even numbers are divisible by 2.

An easy way to see if a number is divisible by two is to look at the last number in it.
the last number in 16,287 is 7... so if you divide 7 by 2, you don't get a whole number. therefore, it is NOT divisible by two! Hope this helps!

No, not an even number...
ex: 16288 would be divisible by 2, but not 16287

you always look at the last digit of your number. it will determine if you have an even or odd number, and thus if it is divisible by 2.

only numbers ending in 0,2,4,6,and8 are divisable by 2
that number end in 7 so no, it is not divisable by 2

Nope, because the last digit 7 is odd
