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 258,628,225, 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 | 258,628,225 | |
| -1 | -258,628,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 258,628,225.
Example:
1 x 258,628,225 = 258,628,225
and
-1 x -258,628,225 = 258,628,225
Notice both answers equal 258,628,225
With that explanation out of the way, let's continue. Next, we take the number 258,628,225 and divide it by 2:
258,628,225 ÷ 2 = 129,314,112.5
If the quotient is a whole number, then 2 and 129,314,112.5 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 | 258,628,225 | |
| -1 | -258,628,225 |
Now, we try dividing 258,628,225 by 3:
258,628,225 ÷ 3 = 86,209,408.3333
If the quotient is a whole number, then 3 and 86,209,408.3333 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 | 258,628,225 | |
| -1 | -258,628,225 |
Let's try dividing by 4:
258,628,225 ÷ 4 = 64,657,056.25
If the quotient is a whole number, then 4 and 64,657,056.25 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 | 258,628,225 | |
| -1 | 258,628,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 79 | 85 | 395 | 425 | 1,343 | 1,975 | 6,715 | 7,703 | 33,575 | 38,515 | 130,951 | 192,575 | 608,537 | 654,755 | 3,042,685 | 3,273,775 | 10,345,129 | 15,213,425 | 51,725,645 | 258,628,225 |
| -1 | -5 | -17 | -25 | -79 | -85 | -395 | -425 | -1,343 | -1,975 | -6,715 | -7,703 | -33,575 | -38,515 | -130,951 | -192,575 | -608,537 | -654,755 | -3,042,685 | -3,273,775 | -10,345,129 | -15,213,425 | -51,725,645 | -258,628,225 |
