144 is divisible by 2, 3, 4, 6, 9 and not divisible by 5 or 10.
The last digit of 144 is 4 and 4 is divisible by 2, thus 144 is divisible by 2.
Sum of the digits of 144 is 1+4+4 = 9 which is divisible by 3, thus 144 is divisible by 3
Last two digits of 144 are 44 which are divisible by 4, thus 144 is divisible by 4
An alternative test: If the last digit plus twice the preceding digit is divisible by 4 then the whole number is divisible by 4.
For 144, last digit + twice preceding digit is 4+2x4 = 12 which is divisible by 4, so 144 is divisible by 4
Last digit of 144 is 4 which is neither 0 nor 5, thus 144 is not divisible by 5
144 is divisible by both 2 and 3 (see above), thus 144 is divisible by 6
For 144, 1+4+4 = 9 which is divisible by 9, thus 144 is divisible by 9
The last digit of 144 is 4 which is not 0, thus 144 is not divisible by 10
It is easier to work backward. All multiples of 144 are automatically divisible by 144. Multiples of 144 are 1*144, 2*144, 3*144, 4*144, ... and -1*144, -2*144, -3*144, -4*144, and so on. =========================
In google search box, type 144/3 and hit return to see the results.-------------------------Yes, 48 * 3 = 144
The digital root (sum of digit) must be divisible by 9, and the number formed by the last 4 digits must be divisible by 16. The second requirement ensures that the number is divisible by 16.
It is evenly divisible by 2 and 10 but not by 3 and 9.
Yes, it is divisible by 2, 3 and 9, but is not exactly divisible by 5 or 10.

9 is divisible by 3 10 is divisible by 2, 5 and 10. Everything else, no.
20 is divisible by 2, 5 and 10. It is not exactly divisible by 3 or 9.
144 is divisible by: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72 and 144.
That means the number itself is divisible by three. the sum of the digits in 144, for example, is 9. 144 divided by 3 is 48. The sum of the digits in 21 is 3. 21 divided by 3 is 7.If the number is an even number and the sum of the digits is divisible by 3, the number is also divisible by 6. 144 is even and the sum of the digits is divisible by 3, so 144 is also divisible by 6. 144/6 = 24. And finally, if the sum is divisible by 9, the number itself is also divisible by 9. 27 is an example of this.
It is divisible by 2, 5 and 10, but not 3 and 9.
