How do you find out what is divisible by 3?

Add up the digits in the number. If the total is a multiple of 3, the entire number will be a multiple of 3.


Is 4339 divisible by 3?

No. To find if a number is a factor of 3, add the number's digits. If the resulting number is a multiple of 3, then the original number is a multiple of 3. In 4339, the digits of the number added together is 19, which is not a multiple of 3.


How do you find a multiple?

A multiple of a number is something you get when you multiply that number by another. For instance, 5 x 2 = 10, so 10 is a MULTIPLE of 5 and a MULTIPLE of 2. If you're trying to find a multiple of a number, say, 3, multiply that number by another. It can be any number.


What number between 55 and 101 that is a multiple of 3 6 8?

To find a number between 55 and 101 that is a multiple of 3, 6, and 8, we need to find the least common multiple (LCM) of 3, 6, and 8. The LCM of 3, 6, and 8 is 24. To find a number between 55 and 101 that is a multiple of 24, we can start with 72 (the smallest multiple of 24 greater than 55) and check if it is less than 101. Therefore, the number between 55 and 101 that is a multiple of 3, 6, and 8 is 72.


What is the least common multiple of 3 and?

It would help to have that other number. If the other number is a multiple of 3, the LCM is that number. If it is not a multiple of 3, the LCM is 3 times that number.


What is the multiple of three out of these numbers 285770126176410452650?

I'll guess those are three-digit numbers. The way to find if a number is a multiple of 3 is to total its digits. If that total is a multiple of 3, the whole number is a multiple of 3. 285 and 126, yes. 770, 176, 410, 452, 650, no.


How do you find out if a number is divisible by three?

Add up the digits. If that total is a multiple of 3, so is the original number.


Is 92 a multiple of 3?

No, 92 is not a multiple of 3. A quick way to check if a number is a multiple of 3 is: add up the digits of the number you are checking; if this sum equals 3 or a multiple of 3, then the number is a multiple of 3. So in this case, 92 --> 9+2=11, which is not a multiple of 3. If you have to you can add again, so for 11 --> 1+1=2, which is not a multiple of 3. You can always repetitively add until you get to a single digit answer: if it's 3,6 or 9 then it's a multiple of 3. Also if your sum is 9 or a multiple of 9, then the original number is a multiple of 9. To check for 6, if a number is a multiple of 3, and also a multiple of 2 (an even number), then the number is a multiple of 6.


Which number is a common multiple of 2 and 3?
