 A:
Positive:   1 x 609777 x 871131 x 1967217 x 281
Negative: -1 x -60977-7 x -8711-31 x -1967-217 x -281


How do I find the factor combinations of the number 60,977?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 60,977, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.

1 60,977
-1 -60,977

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,977.

Example:
1 x 60,977 = 60,977
and
-1 x -60,977 = 60,977
Notice both answers equal 60,977

With that explanation out of the way, let's continue. Next, we take the number 60,977 and divide it by 2:

60,977 ÷ 2 = 30,488.5

If the quotient is a whole number, then 2 and 30,488.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 60,977
-1 -60,977

Now, we try dividing 60,977 by 3:

60,977 ÷ 3 = 20,325.6667

If the quotient is a whole number, then 3 and 20,325.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 60,977
-1 -60,977

Let's try dividing by 4:

60,977 ÷ 4 = 15,244.25

If the quotient is a whole number, then 4 and 15,244.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 60,977
-1 60,977
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:

17312172811,9678,71160,977
-1-7-31-217-281-1,967-8,711-60,977
