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 125,392,475, 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 | 125,392,475 | |
| -1 | -125,392,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,392,475.
Example:
1 x 125,392,475 = 125,392,475
and
-1 x -125,392,475 = 125,392,475
Notice both answers equal 125,392,475
With that explanation out of the way, let's continue. Next, we take the number 125,392,475 and divide it by 2:
125,392,475 ÷ 2 = 62,696,237.5
If the quotient is a whole number, then 2 and 62,696,237.5 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 | 125,392,475 | |
| -1 | -125,392,475 |
Now, we try dividing 125,392,475 by 3:
125,392,475 ÷ 3 = 41,797,491.6667
If the quotient is a whole number, then 3 and 41,797,491.6667 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 | 125,392,475 | |
| -1 | -125,392,475 |
Let's try dividing by 4:
125,392,475 ÷ 4 = 31,348,118.75
If the quotient is a whole number, then 4 and 31,348,118.75 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 | 125,392,475 | |
| -1 | 125,392,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 47 | 65 | 235 | 325 | 611 | 1,175 | 3,055 | 8,209 | 15,275 | 41,045 | 106,717 | 205,225 | 385,823 | 533,585 | 1,929,115 | 2,667,925 | 5,015,699 | 9,645,575 | 25,078,495 | 125,392,475 |
| -1 | -5 | -13 | -25 | -47 | -65 | -235 | -325 | -611 | -1,175 | -3,055 | -8,209 | -15,275 | -41,045 | -106,717 | -205,225 | -385,823 | -533,585 | -1,929,115 | -2,667,925 | -5,015,699 | -9,645,575 | -25,078,495 | -125,392,475 |
