By doing the math in your head on a piece of paper or with your fingers.
You should know 3, 6, and 9 are multiples of three, but for 2-digit numbers or larger you can add the digits and if they equal 3, 6, or 9 then they are multiples of 3.
For example, 15 would be 1 + 5, which is 6, so it's a multiple of 3.
you subtract it from 3hunna
Nope - it's a prime number !
is it 657

I am guessing you want to know what number times 3 is 27. The answer is 9.
you subtract it from 3hunna
They know this because 3 is a factor of 402, therefore 3 multiplied by a number(134 to be precise) will give the quotinent 402 so 402 is therefore in the 3 times table.
175 is not a multiple of 3, so it doesn't appear on the 3 times table.
Yes.Yes.Yes.Yes.
Nope - it's a prime number !

say if you had to find the LCM of 4 and 3 you can go up in the 4 times table or the 3 times table (4times table will be quicker because it's a bigger number) 4 times table= 4, 8, 12, 16, 20, 24, 28 3 times table= 3, 6, 9, 12, 15, 18, 21 find the number that is in both times tables (has to be the LOWEST common number) in this case is 12 because it is in both lists. Once your able to do this, you'll get use to the idea and you can think of other ways to do it, but this way is good for people that have just started. It would be easier if you know all of your times tables up to 10.

All numbers in the 3 times table. For example; 3, 6, 9, 12 . . .
Oh, isn't that a happy little question! Let's take a moment to appreciate the number 45. It goes into the 1 times table, the 3 times table, the 5 times table, the 9 times table, the 15 times table, and of course, the 45 times table. Just remember, every number has its own special place in the world of mathematics.
