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 28,534,513, 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 | 28,534,513 | |
| -1 | -28,534,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,534,513.
Example:
1 x 28,534,513 = 28,534,513
and
-1 x -28,534,513 = 28,534,513
Notice both answers equal 28,534,513
With that explanation out of the way, let's continue. Next, we take the number 28,534,513 and divide it by 2:
28,534,513 ÷ 2 = 14,267,256.5
If the quotient is a whole number, then 2 and 14,267,256.5 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 | 28,534,513 | |
| -1 | -28,534,513 |
Now, we try dividing 28,534,513 by 3:
28,534,513 ÷ 3 = 9,511,504.3333
If the quotient is a whole number, then 3 and 9,511,504.3333 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 | 28,534,513 | |
| -1 | -28,534,513 |
Let's try dividing by 4:
28,534,513 ÷ 4 = 7,133,628.25
If the quotient is a whole number, then 4 and 7,133,628.25 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 | 28,534,513 | |
| -1 | 28,534,513 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 49 | 161 | 343 | 1,127 | 3,617 | 7,889 | 25,319 | 83,191 | 177,233 | 582,337 | 1,240,631 | 4,076,359 | 28,534,513 |
| -1 | -7 | -23 | -49 | -161 | -343 | -1,127 | -3,617 | -7,889 | -25,319 | -83,191 | -177,233 | -582,337 | -1,240,631 | -4,076,359 | -28,534,513 |
