There are an infinite number of multiples of 6 (numbers that six can divide into evenly with no remainder). Without using a calculator, you can determine if a number is a multiple of 6. To be a multiple of 6, it must have both 3 and 2 as factors. So if the number is even, then 2 is a factor. To determine if it is even, look at the ones digit, and if it is (0,2,4,6, or 8) then it's even. Then to determine if 3 is a factor, add the digits in the number, if this sum is a multiple of 3, then the number is also a multiple of 3 (or you could say 3 is a factor). If both of these are true, then the number is a multiple of 6. Example: 984: Last digit (ones digit) is 4, so it's even. Sum 9+8+4=21, which is a multiple of 3, so the number is a multiple of 3. Therefore it is a multiple of 6.

That's the definition of an even number. If they didn't have 2 as a factor, they wouldn't be even.

Any number that is divisible by 2 and is a multiple of that particular number is called an even multiple. Ex: The even multiples of 7 are: 14, 28 etc

Because your beginning number was a multiple of 2.

No. Since 4 is an even number, then any multiple of 4 will also be an even number. An even number will have an even digit in its ones place (0,2,4,6, or 8).

The presence of any even factor says that the numberis a multiple of 2, or a so-called "even" number.

Yes.Yes, 2 is always a factor of a number if it's even but iff it's not even then it's not a multiple of 2 :))))

An even number can be a multiple of an odd number OR an even number. An odd number cannot be a multiple of an even number.

It CAN'T be even, since the number 2 is not a factor of the odd number. "Even" means that a number is a multiple of 2.

By definition, an even number is a multiple of 2. That's what "even" means.

No odd number has an even factor.

Any even number has at least one even factor.

Every number to which 2 is a factor. Therefore, every multiple of two; hence, every even number.

189 is a composite. Some quick tests, which can be done in your head: Check if the number is even (2 is a factor). Ones place will have 0,2,4,6, or 8 if even. Multiple of 5 (5 is a factor): Ones digit is 0 or 5. Multiple of 3 or 9: Add up the digits in the number; if this sum is 3 or a multiple of 3, then the original number is a multiple of 3 (3 is a factor). Additionally, if this sum equals 9 or a multiple of 9, then 9 is a factor. This is the case for 189 : 1+8+9=18, which is a multiple of 9. Since we found a factor (in addition to 1 & the original number) then the number is composite and not prime.
