Which Number Is Not A Factor Of 114?A. 19 B. 4 C. 2 D. 57
Introduction
In mathematics, factors are the numbers that can be multiplied together to get a specific number. For instance, the factors of 6 are 1, 2, 3, and 6. Factors play a crucial role in various mathematical operations, including division and multiplication. In this article, we will explore the factors of 114 and determine which number is not a factor of 114.
Factors of 114
To find the factors of 114, we need to identify the numbers that can be multiplied together to get 114. We can start by listing the numbers from 1 to 114 and checking if they can be divided evenly by 114. Alternatively, we can use the prime factorization method to find the factors of 114.
Prime Factorization of 114
The prime factorization of 114 is 2 x 3 x 19. This means that 114 can be expressed as the product of these three prime numbers.
Factors of 114
Using the prime factorization method, we can find the factors of 114 as follows:
- 1 x 114 = 114
- 2 x 57 = 114
- 3 x 38 = 114
- 6 x 19 = 114
- 19 x 6 = 114
- 38 x 3 = 114
- 57 x 2 = 114
- 114 x 1 = 114
As we can see, the factors of 114 are 1, 2, 3, 6, 19, 38, 57, and 114.
Which Number is Not a Factor of 114?
Now that we have identified the factors of 114, we can determine which number is not a factor of 114. The options are A. 19, B. 4, C. 2, and D. 57.
Option A: 19
As we have seen earlier, 19 is a factor of 114. Therefore, option A is not the correct answer.
Option B: 4
We have not listed 4 as a factor of 114. In fact, 4 is not a factor of 114. To verify this, we can try dividing 114 by 4. We get 28.5, which is not a whole number. Therefore, option B is the correct answer.
Option C: 2
As we have seen earlier, 2 is a factor of 114. Therefore, option C is not the correct answer.
Option D: 57
As we have seen earlier, 57 is a factor of 114. Therefore, option D is not the correct answer.
Conclusion
In conclusion, the number that is not a factor of 114 is option B, which is 4. This is because 4 is not a factor of 114, as it cannot be divided evenly by 114.
