Introduction to Prime Factors

In mathematics, prime factors are the prime numbers that multiply together to create a given number. Understanding prime factors is crucial in determining whether a number is a factor of another number. In this article, we will explore how to use prime factors to determine whether 90 is a factor of 250.

What are Prime Factors?

Prime factors are the prime numbers that divide a given number exactly without leaving a remainder. For example, the prime factors of 12 are 2 and 3, because 2 x 2 x 3 = 12. Prime factors are unique to each number and are used to express a number in its most basic form.

Finding Prime Factors

To find the prime factors of a number, we need to divide the number by the smallest prime number, which is 2, and continue dividing until we cannot divide the number by 2 anymore. Then, we move on to the next prime number, which is 3, and repeat the process. We continue this process until we have divided the number by all prime numbers.

Prime Factors of 90

To find the prime factors of 90, we start by dividing 90 by 2, which gives us 45. We can continue dividing 45 by 2, which gives us 22.5. However, we cannot divide 22.5 by 2 anymore, so we move on to the next prime number, which is 3. Dividing 22.5 by 3 gives us 7.5. We can continue dividing 7.5 by 3, which gives us 2.5. However, we cannot divide 2.5 by 3 anymore, so we move on to the next prime number, which is 5. Dividing 2.5 by 5 gives us 0.5. However, we cannot divide 0.5 by 5 anymore, so we move on to the next prime number, which is 7. However, 7 is not a factor of 90, so we move on to the next prime number, which is 11. However, 11 is not a factor of 90, so we move on to the next prime number, which is 13. However, 13 is not a factor of 90, so we move on to the next prime number, which is 17. However, 17 is not a factor of 90, so we move on to the next prime number, which is 19. However, 19 is not a factor of 90, so we move on to the next prime number, which is 23. However, 23 is not a factor of 90, so we move on to the next prime number, which is 29. However, 29 is not a factor of 90, so we move on to the next prime number, which is 31. However, 31 is not a factor of 90, so we move on to the next prime number, which is 37. However, 37 is not a factor of 90, so we move on to the next prime number, which is 41. However, 41 is not a factor of 90, so we move on to the next prime number, which is 43. However, 43 is not a factor of 90, so we move on to the next prime number, which is 47.
