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 9,175,621, it is easier to work with a table - it's called factoring from the outside in.
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 | 9,175,621 | |
| -1 | -9,175,621 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,175,621.
Example:
1 x 9,175,621 = 9,175,621
and
-1 x -9,175,621 = 9,175,621
Notice both answers equal 9,175,621
With that explanation out of the way, let's continue. Next, we take the number 9,175,621 and divide it by 2:
9,175,621 ÷ 2 = 4,587,810.5
If the quotient is a whole number, then 2 and 4,587,810.5 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 | 9,175,621 | |
| -1 | -9,175,621 |
Now, we try dividing 9,175,621 by 3:
9,175,621 ÷ 3 = 3,058,540.3333
If the quotient is a whole number, then 3 and 3,058,540.3333 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 | 9,175,621 | |
| -1 | -9,175,621 |
Let's try dividing by 4:
9,175,621 ÷ 4 = 2,293,905.25
If the quotient is a whole number, then 4 and 2,293,905.25 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 | 9,175,621 | |
| -1 | 9,175,621 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 59 | 91 | 413 | 767 | 1,709 | 5,369 | 11,963 | 22,217 | 100,831 | 155,519 | 705,817 | 1,310,803 | 9,175,621 |
| -1 | -7 | -13 | -59 | -91 | -413 | -767 | -1,709 | -5,369 | -11,963 | -22,217 | -100,831 | -155,519 | -705,817 | -1,310,803 | -9,175,621 |
