Yes.
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.
144
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. =========================
Oh, what a lovely question! Let's take a moment to explore together. Yes, 144 is divisible by 2, 3, 4, 6, 9, and 12. It's like a happy little tree with many branches reaching out to different numbers. Just remember, numbers can be friends and play nicely together in the world of math.
165 is wholly divisible by 3. This is because 165 can be represented in the form k*3 = l, where k is a positive integer.
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.
A number is divisible by 15 if it is divisible by 5, and by 3. For example, 165 is divisible by 15, since it ends in 5, and the sum of its digits is divisible by 3.
No, 144 and 165 are not relatively prime. For them to be relatively prime, the number 1 could be their only common factor, but they also have 3 as a common factor.
In google search box, type 144/3 and hit return to see the results.-------------------------Yes, 48 * 3 = 144
432 is divisible by 3 and 4 because the quotients are whole numbers. 432/3 = 144 432/4 = 108
108, 144, 180 and so on.
135. Every increase of 30 is also. Such as 165, 195, 225.
