39 is not a prime number.
To identify the number classified as prime among the given options, we need to determine if each number can only be divided evenly by 1 and itself. Here's how you can do it:
1. Start by checking each number from the given options.
2. For each number, start with the smallest possible divisor, which is 2.
3. Divide the number by the divisor.
4. If there is no remainder (i.e., the division results in a whole number), proceed to check for higher divisors.
5. If there is a remainder, move on to the next number and repeat steps 2-5.
6. Continue this process until you have checked all the numbers.
Now let's go through the options one by one:
29:
- Divide 29 by 2: Remainder = 29 % 2 = 1
- Divide 29 by 3: Remainder = 29 % 3 = 2
- Continue dividing by higher numbers until you reach 29: Remainder = 29 % 29 = 0
Since 29 can only be divided evenly by 1 and itself, it is classified as a prime number.
49:
- Divide 49 by 2: Remainder = 49 % 2 = 1
- Divide 49 by 3: Remainder = 49 % 3 = 1
- Divide 49 by 4: Remainder = 49 % 4 = 1
- Continue dividing by higher numbers until you reach 49: Remainder = 49 % 49 = 0
Since 49 can be divided evenly by numbers other than 1 and itself (e.g., 7), it is not classified as a prime number.
69:
- Divide 69 by 2: Remainder = 69 % 2 = 1
- Divide 69 by 3: Remainder = 69 % 3 = 0
Since 69 can be divided evenly by 3 and other numbers (e.g., 23), it is not classified as a prime number.
39:
- Divide 39 by 2: Remainder = 39 % 2 = 1
- Divide 39 by 3: Remainder = 39 % 3 = 0
Since 39 can be divided evenly by 3 and other numbers (e.g., 13), it is not classified as a prime number.
Based on the above analysis, the only number classified as prime among the given options is 29.
