Any even number (except 2) is NOT prime - it is divisible by 2. An even number is (by definition) a multiple of 2; but it can quickly be recognized by the last digit. If the last digit is 0, 2, 4, 6, or 8, the number is even.Any even number (except 2) is NOT prime - it is divisible by 2.

Everything that has 0 as its digit can be divided by both 2, and 5 as well as many more. Therefore it cannot be a prime number.
to be divisible by 5 the last digit of the number has to be 0 or 5
0, 2, 4, 6, or 8
97A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 97 is the largest 2 digit prime number.
If two of the prime factors are 2 and 5, the last digit of the number will be zero.

"Composite" means that the number has smaller factors; "prime" means that it doesn't. Look at the last digit. If the digit is 0, 2, 4, 6, or 8, the number is divisible by 2. If the last digit is 0 or 5, the number is divisible by 5. If it none of those, the number may still have additional factors; but checking for this last digit can often quickly give you an answer.
No even number is a prime number - except 2. If the last digit is 0, 2, 4, 6, or 8, the number is divisible by 2, and therefore not a prime number.
All numbers ending in 0 and 5 are divisible by 5 and since 28655 ends in 5, it is divisible by 5 and therefore not prime.
Everything that has 0 as its digit can be divided by both 2, and 5 as well as many more. Therefore it cannot be a prime number.
to be divisible by 5 the last digit of the number has to be 0 or 5
0, 2, 4, 6, or 8
97A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 97 is the largest 2 digit prime number.
55 has factors other than 1 and itself, so it is not a prime number. For example, 55 is divisible by 5. (You can tell this because the last digit is a 5. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 55 is a composite number.composite
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 360 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 5. (You can tell this because the last digit is a 0. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 360 is a composite number.
2005The ones digit is 5.If the ones digit is 5 or 0 then it is divisible by5.NOT a prime.
