Answer for screen readers
The prime factors of 46 are $2$ and $23$.
Steps to Solve
-
Identify the First Prime Number Start with the smallest prime number, which is 2. Check if 2 divides 46 evenly. $$ 46 \div 2 = 23 $$
-
Check the Resulting Quotient After dividing, we find that 23 is the quotient. Now we need to check if 23 is a prime number.
-
Determine if 23 is Prime We check if any prime numbers (up to the square root of 23) divide 23 without a remainder. The prime numbers less than or equal to 5 (since $5^2 = 25 > 23$) are 2, 3, and 5.
- Dividing by 2: 23 is not even, so not divisible.
- Dividing by 3: $23 \div 3$ does not yield an integer.
- Dividing by 5: $23 \div 5$ also does not yield an integer.
Since 23 is not divisible by any of these, it is a prime number.
- Combine the Prime Factors We can now state that the prime factorization of 46 is the product of the two prime numbers found: $$ 2 \times 23 $$
The prime factors of 46 are $2$ and $23$.
More Information
The number 46 is not a prime number itself because it can be divided by other numbers (in this case, 2 and 23). Understanding prime factorization helps in various areas of mathematics, including simplifying fractions and finding the greatest common divisor.
Tips
- Confusing composite numbers with prime numbers: Remember that prime numbers only have two factors, 1 and themselves.
- Not checking all relevant prime numbers to determine the primality of a quotient.
