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.

101 is not a multiple of 3. The easiest way to check if a number is the same multiple of another is to divide the biggest number by the smallest, eg. 101/3 = 33.666... The closest multiples of 3 is 102 or even 99.

Yes. 1+0+8 = 9 = 3 x 3 so 108 is a multiple of 3, thus it appears in the 3 times table [To check if a number is a multiple of 3, add its digits together and if the sum is a multiple of 3 then the original number is a multiple of 3.] [108 = 3 x 36]

No. To check if a number is a multiple of 3 add its digits together and if this sum is a multiple of 3, then so is the original number. This sum can be continued until a single digit remains; if the single digit is 3, 6 or 9 then the original number is a multiple of 3, otherwise not. 19 → 1 + 9 = 10 10 → 1 + 0 = 1 which is not 3, 6 or 9, so 19 is not a multiple of 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.

Check it out: 4,8,12,16,20,24,28,32,36. No threes.

753/3 = 251. As an easy check for divisibility by 3, add the digits of the number. If the sum is 3 or a multiple of 3, then 3 will divide into the number.

Yes, 345 is a multiple of 3. One easy way to check whether a large number is a multiple of 3 is to add its digits, and see if they are divisible by 3. 3+4+5 = 12, which is divisible by 3.

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.

To check for divisibility by three:Add together the digits in the number. If the total is a multiple of 3 then the number is divisible by three.E.g. 5830. 5 + 8 + 3 + 0 = 16. Since 16 is not a multiple of three then 5830 is not divisible by three.

If the number is even, it is a multiple of 2 If the sum of the digits make a number divisible by 3, the number is a multiple of 3 If the number ends in 5 or 0, the number is a multiple of 5 If the number is divisible by 2 and 3, the number is a multiple of 6 If the sum of the digits make a number divisible by 9, the number is a multiple of 9

you add up the digits, and if the sum is a multiple of 3, then the number is divisible by 3!
