What can 99 be divisible by?
Since the answer to our division is a whole number, we know that 99 is divisible by 3. Hopefully now you know exactly how to work out whether one number is divisible by another.
Is 99 divisible by 9 yes or no?
99, 198, 171, 9990, 3411. Sum of the digits of 99 = 9 + 9 = 18, which is divisible by 9. Hence, 99 is divisible by 9.
Is 99 a perfect number?
99 is not a perfect square.
What numbers can divide into 9?
The factors of 9 are 1, 3, 9 and the factors of 7 are 1, 7. 9 and 7 have only one common factor which is 1. This implies that 9 and 7 are co-prime. Hence, the Greatest Common Factor (GCF) of 9 and 7 is 1.
How many numbers amongst the numbers 9 to 99 are there which are exactly divisible by 9 but not by 3?
The numbers which are divisible by 9 are 18, 27, 36 and 45. Since 9 = 3 × 3, it is not possible for any number to exist with the condition to be exactly divided by 9, but not by 3. However there are numbers which are exactly divisible 3, but not by 9 and they are 12, 15, 21, 24, 30, 33, 39, 42, 48 and 51.
Which of the following is a rule for divisibility by 9?
If the sum of the digits of a number is divisible by 9, then the number is divisible by 9. Some examples of numbers divisible by 9 are as follows. The number 51984 is divisible by 9 because the sum of its digits 5+1+9+8+4=27 is divisible by 9.
What can 12 be divided by?
Factors of 12 are 1, 2,3,4,6, and 12. So the number 12 will be divisible by 1,2,3,4,6 and 12.
Can 4 be divided by 2?
Using a calculator, if you typed in 4 divided by 2, you’d get 2.
What can 10 be divided by?
The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10. 1 x 10 = 10, so 1 and 10 are also factors of 10.
What can 18 be divided by?
When we list them out like this it’s easy to see that the numbers which 18 is divisible by are 1, 2, 3, 6, 9, and 18.
What can 16 be divided by?
For example, 16 can be divided evenly by 1, 2, 4, 8, and 16. So the numbers 1, 2, 4, 8, and 16 are called factors of 16. To find the factors of a number, begin with 1 and the number itself, then divide the number by 2, 3, 4, etc., taking only pairs of factors that divide the number evenly.
What can 24 be divided by?
Let us see which numbers divide 24 exactly without a remainder in which case the divisors, as well as the quotients, are the factors of 24. Hence, the factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.
