What 2 digit numbers are divisible by 3 but not by 6?
Since 3 is a factor of 6, any number divisible by 6 is also divisible by 3. But since 2 is also a factor of 6, then any number divisible by 6 must also be divisible by 2. This means that any number divisible by 6 is an even number. So if a number is odd and it is divisible by 3, then it is not divisible by 6. For example, 12 is divisible by 3, but since it is even, it is also divisible by 6. But 15 is divisible by 3, and it is odd, so it is not divisible by 6.
Is every number that is divisible by 6 divisible by 3?
Yes, it's true. 3 is one of the factors of 6, so any number that has six as a factor also has 3 as a factor.
How do you know when a number has 6 as a factor?
First you add up all of the digit's, and then divide. If 6 fits in it, then 3 also fits in it, but not 9. (For ex. Is 6 a factor of 674. 6+7+4=17, 17/6=2.8. so no, 6 is not a factor of 674) If your number is even and divisible by three, it's divisible by 6.
If the last digit of a number is 6 then is 6 a factor?
Not necessarily. For example, the number 56 ends in a 6 but is not divisible by six. To check if a number is divisible by six, the number must be divisible by both 2 and 3. To check this, the last digit must be even and the sum of the digits must be divisible by three. If the number meets these conditions, it is in fact divisible by six.
What is the divisible by 6?
If a number is divisible by 2 and 3, it is divisible by 6.
Is the factors of a number an divisible by a number the same thing?
Yes. If a number is divisible by another number, that second number is a factor of the first. 6 is divisible by 2, 2 is a factor of 6.
What 2 digit numbers are divisible by 3 but not by 6?
Since 3 is a factor of 6, any number divisible by 6 is also divisible by 3. But since 2 is also a factor of 6, then any number divisible by 6 must also be divisible by 2. This means that any number divisible by 6 is an even number. So if a number is odd and it is divisible by 3, then it is not divisible by 6. For example, 12 is divisible by 3, but since it is even, it is also divisible by 6. But 15 is divisible by 3, and it is odd, so it is not divisible by 6.
Is every number that is divisible by 6 divisible by 3?
Yes, it's true. 3 is one of the factors of 6, so any number that has six as a factor also has 3 as a factor.
Is 6 a factor of492 explain how you know?
492 is an even number so it must be divisible by 2. Its digits total a multiple of 3 so it must be divisible by 3. Any even number that is divisible by 3 is divisible by 6. Of course, you can always divide 492 by 6. If it comes out even, it's a factor. (It does.)

How is 6 a factor of 234?
234 is even and divisible by three. It has to be divisible by 6.
What odd number is divisible by 6?
No odd number can be evenly divisible by 6. Since 6 is divisible by 2, any number that is divisible by 6 will automatically be divisible by 2.
What number is divisible by 6 but not 3?
There is no such number. Since 6 is divisible by 3, then any number that is divisible by 6 automatically has to be divisible by 3.
Is 138 divisible by 6?
138 is divisible by 6. Any number is divisible by 6 if it is an even number that also is divisible by 3.
How can you know if 6 is a factor of 78?
For a number to be divisible by 6, it has to be divisible by 2 and 3, because 2*3=6.In other words, we could divide the number we're factorising (78) by the prime factors of the number we're testing (6, which is 2*3). We start by dividing by 2, because we know 78 is even: 78/2=39. Then, we divide the new number by the other prime factor - 3. 39/3=13 13 is a whole number with no remainders, therefore we can say that 78 is divisible by 6, and therefore 6 is a factor of 78. (6*13=78)
What is the highest factor of 2530 that is not divisible by 6?
The highest factor of 2,530 that is not divisible by six is 2,530 itself.
