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 230,201,525, 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 | 230,201,525 | |
| -1 | -230,201,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,201,525.
Example:
1 x 230,201,525 = 230,201,525
and
-1 x -230,201,525 = 230,201,525
Notice both answers equal 230,201,525
With that explanation out of the way, let's continue. Next, we take the number 230,201,525 and divide it by 2:
230,201,525 ÷ 2 = 115,100,762.5
If the quotient is a whole number, then 2 and 115,100,762.5 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 | 230,201,525 | |
| -1 | -230,201,525 |
Now, we try dividing 230,201,525 by 3:
230,201,525 ÷ 3 = 76,733,841.6667
If the quotient is a whole number, then 3 and 76,733,841.6667 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 | 230,201,525 | |
| -1 | -230,201,525 |
Let's try dividing by 4:
230,201,525 ÷ 4 = 57,550,381.25
If the quotient is a whole number, then 4 and 57,550,381.25 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 | 230,201,525 | |
| -1 | 230,201,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 53 | 71 | 265 | 355 | 1,325 | 1,775 | 2,447 | 3,763 | 12,235 | 18,815 | 61,175 | 94,075 | 129,691 | 173,737 | 648,455 | 868,685 | 3,242,275 | 4,343,425 | 9,208,061 | 46,040,305 | 230,201,525 |
| -1 | -5 | -25 | -53 | -71 | -265 | -355 | -1,325 | -1,775 | -2,447 | -3,763 | -12,235 | -18,815 | -61,175 | -94,075 | -129,691 | -173,737 | -648,455 | -868,685 | -3,242,275 | -4,343,425 | -9,208,061 | -46,040,305 | -230,201,525 |
