No, there are composite numbers that end in every other digit.
7, 31, 103 All three are prime numbers and not composite numbers.
111 and 201
All whole, three-digit numbers from 450 through 549 (when rounding to the nearest hundreds).
There are 900 three-digit numbers.
well, it's not 999 because that's odd ... can't see why it wouldn't be 998, which is the greatest even three-digit number, and since all even numbers besides 2 are composite, it must also be the greatest three-digit composite even number
Work back from 999:999 is odd ... no.998 is even and divisible by 2, so it is composite. (All even numbers are composite!)Further Information:-All even numbers are composite except for 2 which is a prime number.
3, 6, 9
All five digit numbers have three digits. The smallest five digit whole number is 10,000
For any integer greater than 5, where the units digit is 5 then that number can be expressed as the product of n and 5. As such, the number is composite. Therefore all numbers in the range 150 to 200 that have a units digit of 5 are composite,.
Not all composite numbers are even, but all even numbers except 2 are composite.
The least 1 digit number that is composite is 4. It is because all numbers before that are prime.
