What are the divisibility rules to find at least four factors of the number 312?
use divisibility rules to find at least four factors of the number 19
Which numbers from the divisibility rules list divide the number 1840?
The answer will depend on the divisibility rules list.
Is 312 divisible by 3?
Yes. 312 / 3 = 104Because, using your divisibility rules you know that the sum of the numbers (3+1+2) is 6 which is a multiple of 3. threfor you can say, that is does devide by three.
What divisibility rules were combined to make the divisibility rule of 36?
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
How can knowing the divisibility rules help to determine if a number is prime or composite?
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.
