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 28,565,341, 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 | 28,565,341 | |
| -1 | -28,565,341 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,565,341.
Example:
1 x 28,565,341 = 28,565,341
and
-1 x -28,565,341 = 28,565,341
Notice both answers equal 28,565,341
With that explanation out of the way, let's continue. Next, we take the number 28,565,341 and divide it by 2:
28,565,341 ÷ 2 = 14,282,670.5
If the quotient is a whole number, then 2 and 14,282,670.5 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 | 28,565,341 | |
| -1 | -28,565,341 |
Now, we try dividing 28,565,341 by 3:
28,565,341 ÷ 3 = 9,521,780.3333
If the quotient is a whole number, then 3 and 9,521,780.3333 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 | 28,565,341 | |
| -1 | -28,565,341 |
Let's try dividing by 4:
28,565,341 ÷ 4 = 7,141,335.25
If the quotient is a whole number, then 4 and 7,141,335.25 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 | 28,565,341 | |
| -1 | 28,565,341 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 397 | 541 | 2,779 | 3,787 | 7,543 | 10,279 | 52,801 | 71,953 | 214,777 | 1,503,439 | 4,080,763 | 28,565,341 |
| -1 | -7 | -19 | -133 | -397 | -541 | -2,779 | -3,787 | -7,543 | -10,279 | -52,801 | -71,953 | -214,777 | -1,503,439 | -4,080,763 | -28,565,341 |
