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 245,532,125, 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 | 245,532,125 | |
| -1 | -245,532,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,532,125.
Example:
1 x 245,532,125 = 245,532,125
and
-1 x -245,532,125 = 245,532,125
Notice both answers equal 245,532,125
With that explanation out of the way, let's continue. Next, we take the number 245,532,125 and divide it by 2:
245,532,125 ÷ 2 = 122,766,062.5
If the quotient is a whole number, then 2 and 122,766,062.5 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 | 245,532,125 | |
| -1 | -245,532,125 |
Now, we try dividing 245,532,125 by 3:
245,532,125 ÷ 3 = 81,844,041.6667
If the quotient is a whole number, then 3 and 81,844,041.6667 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 | 245,532,125 | |
| -1 | -245,532,125 |
Let's try dividing by 4:
245,532,125 ÷ 4 = 61,383,031.25
If the quotient is a whole number, then 4 and 61,383,031.25 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 | 245,532,125 | |
| -1 | 245,532,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 125 | 145 | 725 | 3,625 | 67,733 | 338,665 | 1,693,325 | 1,964,257 | 8,466,625 | 9,821,285 | 49,106,425 | 245,532,125 |
| -1 | -5 | -25 | -29 | -125 | -145 | -725 | -3,625 | -67,733 | -338,665 | -1,693,325 | -1,964,257 | -8,466,625 | -9,821,285 | -49,106,425 | -245,532,125 |
