The last 2 digits are divisible by 4
1312 is (12÷4=3) (1312 ÷ 4=328).
7019 is not- so four does not go in (evenly).
That one is great, but I have found one that works too. Divide the number by two, if it is still even- it is a multiple of four. ( Divide in half one more time to get your answer).
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
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

The least 4 factors of 144 are 1, 2, 3, and 4 .
By using the divisibility rule for 3, we find that 117 is divisible by 3. That makes it composite.
There is no easy rule for divisibility by 34.
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
By tautology. If it did not work, it would not be a divisibility rule!
why does the divisibility rule work for 4
1, 2, 4 and 47
1, 2, 3 and 4
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
What is the divisblity rule by 8
The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.
there is a divisibility for 24 the rule is you can divide 24 as 6 and 4 i think
Able to Be Divided
