The answer will depend on the divisibility rules list.
The divisibility rules for a prime number is if it is ONLY divisible by 1, and itself.
use divisibility rules to find at least four factors of the number 19
You can always check on the divisibility of a number by dividing it into another number. But if you know the divisibility rules, you can get that information easier and faster.
they can help you by finding the two factors of the number given
Divisibility rules help you find the factors of a number. Once you've found the factors for two or more numbers, you can find what they have in common. Take 231 and 321. If you know the divisibility rules, you know that they are both divisible by 3, so 3 is a common factor.
The number 0.
the last number should be an even number.
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
If a number is even, then it is divisible by 2.
If a number is divisible by 3 and 5, it is divisible by 15.
It isn't worthwhile to invent or memorize complicated divisibility rules for lots of numbers. Just carrying out the divisions is faster in most cases.
Knowing the divisibility rules will help you by being able to recognize if a number has factors (other than one and itself) which are covered by the rules. This will save actually having to start doing divisions.
If the number is even, it is divisible by 2. If the sum of the digits is a multiple of 3, the whole number is divisible by 3.
the divisibility rule for 2 is: The number is even;the last digit ends with a 2,4,6,8,10, etc.The divisibility rule fir 3 is: The sum of the number is divisible by 3The divisibility rule for 4 is: The last two digits are divisible by 4The divisibility rule for 5 is: The number ends with a 5 or 0The divisibility rule for 6 is: The sum CAN be divisible by 2 and or 3The divisibility rule for 9 is: The sum of the number is divisible by 9The divisibility rule for 10 is : The number ends with a 0
divided by what number use your divisibility rules
If a number is divisible by 3, and also by 4, then it is divisible by 12 - so you might use the divisibility rules for those two numbers. Although it might be simpler just to perform the division.
fractions help you write out divisibility rules because divisibility rules help with fractions . Glad I would help good bye
Divisibility by 48 requires divisibility by 3 AND by 48Divisibility by 3 requires tat the digital root (sum of digits) is divisible by 3.Divisibility by 16 requires that the number formed by the last four digits is divisible by 16.Of both these are satisfied by a number then it is divisible by 48.
If you know that a number is divisible by three, then you know that three and the number that results from the dividing are both factors of the original number. If you know that a number is not divisible by three, then you won't waste time performing that function. It's rare that the first factor other than one isn't a number between two and ten. If you know the divisibility rules, it will make factoring easier and faster.
If the rules for 2 and 3 work, the number is divisibale by 5.
a number is divisible by 9 if the sum of the digits is divisible by 9.
the number is even.
17 is a prime number meaning it is not divisible by anything. There are no factors of 17.
