Is 1218 divisible by 3?
Yes, it is. Your answer is 406. You can determine whether a number is divisible by 3 by adding the digits. If the sum of the digits (in the above, 1+2+1+8 = 12) equals 3, the number is divisible by 3.
How can you Describe a pattern you see in your list that you can use to determine whether a large number such as 1276549 is a divisible by 5?
Any whole number, in order to be divisible by 5, must end in either 0 or 5.
How do you determine whether a number is divisible by three?
you add the numbers together and if that is divisible by three then so is that number for example: the number 111, you would do 1+1+1=3 so 111 is dividable by 3; or the number 1,620, 1+6+2+0= 9 (which is divisible by 3) so 1,620 is divisible by 3
How can your knowledge of divisibility rules help you to determine whether a number is prime or composite?
If a number is divisible by anything other than itself and 1, it's composite.
How could I describe a pattern that I can see in my list that I can use to determine whether a large number such as 1276549 is divisible by 5?
I do not know what pattern you can see!
Determine whether 1 260 is divisible by 2 3 4 5 6 9 10?
The number 1,260 is divisible by 2, 3, 4, 5, 6, 9, and 10.
How do you know if 54132 is divisible by 6?
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.
How do you determine whether a no is prime or not?
A prime number is a positive integer with two factors: one and the number itself. If you test the numbers up to the square root and your number is not divisible by any of them, it's prime.
What is a quick way to determine if 3 is a factor of a number?
If the sum of the digits of a given number is divisible by three, the number is divisible by three.
How can you tell wether a number is even or odd?
To determine if a number is even or odd, you can check if the number is divisible by 2. If the number is divisible by 2 without leaving a remainder, then it is even. If the number is not divisible by 2 or leaves a remainder when divided by 2, then it is odd.
How can you figure out whether a number is divisible by 5?
You can tell whether a number is divisible by 5 by looking at the last digit if there is no decimal point. If the last digit a 5 or 0 then it is divisible by 5. For example 365 or 400
How do you determine whether a prime number is one or not?
A prime number is a positive integer with two factors: one and the number itself. If you test the numbers up to the square root and your number is not divisible by any of them, it's prime.
