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 28,650,341, 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 | 28,650,341 | |
| -1 | -28,650,341 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,650,341.
Example:
1 x 28,650,341 = 28,650,341
and
-1 x -28,650,341 = 28,650,341
Notice both answers equal 28,650,341
With that explanation out of the way, let's continue. Next, we take the number 28,650,341 and divide it by 2:
28,650,341 ÷ 2 = 14,325,170.5
If the quotient is a whole number, then 2 and 14,325,170.5 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 | 28,650,341 | |
| -1 | -28,650,341 |
Now, we try dividing 28,650,341 by 3:
28,650,341 ÷ 3 = 9,550,113.6667
If the quotient is a whole number, then 3 and 9,550,113.6667 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 | 28,650,341 | |
| -1 | -28,650,341 |
Let's try dividing by 4:
28,650,341 ÷ 4 = 7,162,585.25
If the quotient is a whole number, then 4 and 7,162,585.25 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 | 28,650,341 | |
| -1 | 28,650,341 |
If you did it right, you will end up with this table:
| 1 | 23 | 43 | 59 | 491 | 989 | 1,357 | 2,537 | 11,293 | 21,113 | 28,969 | 58,351 | 485,599 | 666,287 | 1,245,667 | 28,650,341 |
| -1 | -23 | -43 | -59 | -491 | -989 | -1,357 | -2,537 | -11,293 | -21,113 | -28,969 | -58,351 | -485,599 | -666,287 | -1,245,667 | -28,650,341 |
