Question

write all the factor of 28​

Answer 1

Answer:

hi

your answer is here !

Step-by-step explanation:

Let's list out the factors of 28: 1, 2, 4, 7, 14, 28. Each of the numbers in this list are factor pairs. We can move from the outsides to the center and pair the numbers together to make sets of numbers that will multiply to make 28.

Answer 2

Step-by-step explanation:

4 and 7 are factors of 28.

You might be thinking that there are other ways to multiply and make 28. You are correct!

You could also multiply 2 x 14 or 1 x 28. These are all factors of 28.

Let's list out the factors of 28: 1, 2, 4, 7, 14, 28. Each of the numbers in this list are factor pairs.

We can move from the outsides to the center and pair the numbers together to make sets of numbers that will multiply to make 28.

Take a look at another example:

List all the factors of 60.

Whenever we are asked to list out all of the factors, we can use these factor pairs to help make sure that we have not missed any. We will start on the outside and work our way in.

The first pair is 1 and 60.

Next, we will divide 60 by 2 because 60 is even. So the second pair is 2 and 30.

From here, we can continue to try the next number up in order. So the third pair is 3 and 20.

Now we will use 4 and 15.

60 ends in a zero, so we can use 5 and 12.

Then we will add 6 and 10.

Now, in between 6 and 10 is 7, 8 and 9. Once we have checked if any of these three numbers will go into 60, we know that we have found all of the factors of 60. None of them will divide evenly into 60. Therefore we have all of the factors of 60 listed above.

Factors are important because they help us solve problems. Factors can help us be able to break things into groups.
