The sum of the individual digits must be a multiple of nine. For example, 711 would be 7+1+1 = 9, which is obviously a multiple of nine. 711 / 9 = 79
3 and 9. And they divide into 123456789 whether or not you use divisibility rules!
If the digit sum of a number is 9 then it is divisible by 9
If the last 3 digits are divisible by 8 and the sum of the digits are divisible by 9.
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 the number is divisible by both 5 and 9, then the number fits into 45 perfectly. 5- If the last digit is 0 or 5 9- If the sum of the digits are divisible by 9 Examples: 61,335, 844,560, 174,555 Non Examples: 4,122, 2085
a number is divisible by 9 if the sum of the digits is divisible by 9.
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
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.
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.
use divisibility rules to find at least four factors of the number 19
3 and 9. And they divide into 123456789 whether or not you use divisibility rules!
The number 0.
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
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.
If the digit sum of a number is 9 then it is divisible by 9
