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 285,040,625, 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 | 285,040,625 | |
| -1 | -285,040,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 285,040,625.
Example:
1 x 285,040,625 = 285,040,625
and
-1 x -285,040,625 = 285,040,625
Notice both answers equal 285,040,625
With that explanation out of the way, let's continue. Next, we take the number 285,040,625 and divide it by 2:
285,040,625 ÷ 2 = 142,520,312.5
If the quotient is a whole number, then 2 and 142,520,312.5 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 | 285,040,625 | |
| -1 | -285,040,625 |
Now, we try dividing 285,040,625 by 3:
285,040,625 ÷ 3 = 95,013,541.6667
If the quotient is a whole number, then 3 and 95,013,541.6667 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 | 285,040,625 | |
| -1 | -285,040,625 |
Let's try dividing by 4:
285,040,625 ÷ 4 = 71,260,156.25
If the quotient is a whole number, then 4 and 71,260,156.25 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 | 285,040,625 | |
| -1 | 285,040,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 53 | 125 | 265 | 625 | 1,325 | 1,721 | 3,125 | 6,625 | 8,605 | 33,125 | 43,025 | 91,213 | 165,625 | 215,125 | 456,065 | 1,075,625 | 2,280,325 | 5,378,125 | 11,401,625 | 57,008,125 | 285,040,625 |
| -1 | -5 | -25 | -53 | -125 | -265 | -625 | -1,325 | -1,721 | -3,125 | -6,625 | -8,605 | -33,125 | -43,025 | -91,213 | -165,625 | -215,125 | -456,065 | -1,075,625 | -2,280,325 | -5,378,125 | -11,401,625 | -57,008,125 | -285,040,625 |
