What are factors?

Factors are the numbers that can be multiplied together to get a specific number. In other words, factors are the integers that can divide a given number without leaving a remainder. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, as these numbers can be multiplied together to equal 12.

How do you find the factors of a number?

To find the factors of a number, you need to divide that number by all possible smaller numbers and check if the division results in a whole number without a remainder. The factors of a number are all the numbers that can divide the given number evenly. By systematically dividing the number by smaller numbers, you can identify and list all the factors of that number.

What is the difference between factors and multiples?

Factors are numbers that can be multiplied together to get a specific number, while multiples are numbers that result from multiplying a number by an integer. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, as these numbers can be multiplied together to get 12. On the other hand, the multiples of 12 are 12, 24, 36, 48, and so on, as these are the results of multiplying 12 by different integers. In summary, factors create a number, while multiples are the results of multiplying a number by different integers.

Can a number be its own factor?

No, a number cannot be its own factor because factors are numbers that can evenly divide into a given number without leaving a remainder. Since a number divided by itself equals 1, not the original number, a number is not considered its own factor.

What is the greatest common factor?

The greatest common factor (GCF) is the largest number that divides evenly into two or more numbers without leaving a remainder. It is the highest value that is a common factor of all the numbers being considered.

Is 1 a factor of every number? Why or why not?

Yes, 1 is a factor of every number because it divides every number evenly without leaving a remainder. This is because 1 multiplied by any number equals that number, making 1 a factor of every number.

How do you determine if a number is prime or composite using factors?

To determine if a number is prime or composite using factors, you need to find its factors by dividing it by numbers starting from 2. If the number has more than two factors (1 and itself), then it is composite. If it only has two factors, 1 and itself, then it is prime. Prime numbers cannot be divided evenly by any other number except 1 and itself, while composite numbers have additional factors beyond just 1 and the number itself.

Are all even numbers divisible by 2? Why or why not?

Yes, all even numbers are divisible by 2. This is because an even number is defined as any integer that is exactly divisible by 2 without leaving a remainder. Thus, by definition, all even numbers can be evenly divided by 2.

Can a number have more than one pair of factors?

Yes, a number can have more than one pair of factors. Factors are numbers that can be multiplied together to obtain the number in question. For example, the number 12 has the pair of factors 1 and 12, as well as the pair of factors 2 and 6. So, a number can have multiple pairs of factors that when multiplied together equal the number.

How can factors help with simplifying fractions?

Factors can help with simplifying fractions by finding common factors between the numerator and denominator. By identifying common factors, you can divide both the numerator and denominator by the greatest common factor to simplify the fraction to its simplest form. This process reduces the fraction to a form where the numerator and denominator have no common factors other than 1, making the fraction easier to work with and understand.
