25. is 16 a prime number? why or why not? 27. which of these numbers is a factor of 12? A 0 B 6 C 8 D 24
Jojo -- we do not do homework assignments on this forum.
If you post your answers, we will check them for you.
16 is NOT prime because there are many numbers that 16 is divisible by.
for your second question, figure out which number goes into 12. The answer would be 6
yes its 6
To determine if 16 is a prime number, we need to check if it has any factors other than 1 and itself. The easiest way to find the factors of a number is by dividing it by prime numbers up to its square root.
Step 1: Start by finding the square root of 16. The square root of 16 is 4.
Step 2: Test prime numbers up to 4 (2 and 3) as potential factors of 16.
- Divide 16 by 2. The result is 8.
- Divide 16 by 3. The result is not a whole number.
Since 16 is divisible by a number other than 1 and itself (8), it is not a prime number.
Now, moving on to the second question: "Which of these numbers is a factor of 12: 0, 6, 8, or 24?"
To find the factors of 12, we need to check which numbers can be divided evenly into 12, resulting in a whole number.
- Divide 12 by 0. Division by 0 is undefined because you cannot divide by zero.
- Divide 12 by 6. The result is 2.
- Divide 12 by 8. The result is not a whole number.
- Divide 12 by 24. The result is not a whole number.
The only number from the options provided that is a factor of 12 is 6 (option B).
