Best Answer

345 is not divisible by 9. A quick rule for checking to see if a number is divisible by 9 is to add all of the number's digits. If their sum is divisible by 9, so is the number.

2+3+4 = 9, which is divisible by 9, so 234 is divisible by 9. (234/9 = 16)

3+4+5 = 123, which is not divisible by 9, so 345 is not divisible by 9 (345/9 = 38 r 3)

5+6+7 = 18, which is divisible by 9, so 567 is divisible by 9 (567/9 = 63)

Yes, 345 is a multiple of 3. One easy way to check whether a large number is a multiple of 3 is to add its digits, and see if they are divisible by 3. 3+4+5 = 12, which is divisible by 3.

Hmmm, this is simple 4th grade math ... one would think with all the electronics in phones and iPods this question would not be asked. But since you did ask it, my PC calculator indicates that 234 x 345 = 80,730.

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. 567 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 5 + 6 + 7 = 18. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 567 is a composite number.

The only even prime is 2, so neither 234 nor 788 is prime. Since 1+2+3=6 is divisible by 3, the divisibility test for 3 says 123 can not be prime. If one of the options must be prime, then we know it is 563. Just to check:563 is odd and not divisible by 3,5,7,11,13,17,19, or 23. Since it is not divisible by any primes less than its square root, we know that 563 is not divisible by any whole numbers other than itself and one and is hence prime.
