Three composite numbers are 1 3 6

No 28 is a composite number and not a multiple of 3

not a prime number as it’s divisible by 1, 63, 3, and 21

First of all, every number is a factor - of its multiples.There is no general way to distinguish between prime and composite numbers. At one level, though, there are some simple ways. If the number is not 2, but ends in 0, 2, 4, 6 or 8 then it is a composite, If the number is not 5 but ends in 0 or 5 it is composite. If the number is not 3 but the sum of all the digits of a number is 3 or divisible by 3, then it is composite. There are moderately complicated divisibility rules for 7 and 11. But this method does not identify all composite numbers and there is no guaranteed method.

147 has factors other than 1 and itself, so it is not a prime number. For example, 147 is divisible by 3. (You can quickly check this by adding up the digits of 147: 1 + 4 + 7 = 12. If the sum of the digits is divisible by 3, so is the number.) Therefore, 147 is a composite number.

891 is a composite number. Its factors are 1, 3, 9, 11, 27, 33, 81, 99, 297, and 891. An easy check for some numbers greater than 3 is by adding their digits. If the sum of the digits is 3 or a multiple of 3, the number is a composite. The digits of 891 add up to 18, which is a multiple of 3.

23, 29 and 31 are prime. The rest are composite.

The number 993 is a composite number because you can divide it by 3. A good strategy for figuring this out on your own is adding up all the digits. If you can divide the sum of the digits by any numbers besides 1 and that number than that number will be a composite number. You can do it, just remember this!

If you mean a composite number that has 2 and 3 as factors of it, then it would be 6 or any other multiple of 6 . If you mean a composite number that has 2 and 3 as digits in it , then it would be 234 or any other such numbers like 324,243,322,332,532,632,etc.

Both numbers are composite numbers. Using the rules of divisibility, 2312 is composite because it is an even number that ends with 0, 2, 4, 6, or 8. 3819 is composite because the sum of its digits equal 21, a number that is divisible by 3, so the number itself is divisible by 3.
