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 8,741,473, 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 | 8,741,473 | |
| -1 | -8,741,473 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,741,473.
Example:
1 x 8,741,473 = 8,741,473
and
-1 x -8,741,473 = 8,741,473
Notice both answers equal 8,741,473
With that explanation out of the way, let's continue. Next, we take the number 8,741,473 and divide it by 2:
8,741,473 ÷ 2 = 4,370,736.5
If the quotient is a whole number, then 2 and 4,370,736.5 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 | 8,741,473 | |
| -1 | -8,741,473 |
Now, we try dividing 8,741,473 by 3:
8,741,473 ÷ 3 = 2,913,824.3333
If the quotient is a whole number, then 3 and 2,913,824.3333 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 | 8,741,473 | |
| -1 | -8,741,473 |
Let's try dividing by 4:
8,741,473 ÷ 4 = 2,185,368.25
If the quotient is a whole number, then 4 and 2,185,368.25 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 | 8,741,473 | |
| -1 | 8,741,473 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 109 | 199 | 403 | 1,417 | 2,587 | 3,379 | 6,169 | 21,691 | 43,927 | 80,197 | 281,983 | 672,421 | 8,741,473 |
| -1 | -13 | -31 | -109 | -199 | -403 | -1,417 | -2,587 | -3,379 | -6,169 | -21,691 | -43,927 | -80,197 | -281,983 | -672,421 | -8,741,473 |
