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 125,074,523, 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 | 125,074,523 | |
| -1 | -125,074,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,074,523.
Example:
1 x 125,074,523 = 125,074,523
and
-1 x -125,074,523 = 125,074,523
Notice both answers equal 125,074,523
With that explanation out of the way, let's continue. Next, we take the number 125,074,523 and divide it by 2:
125,074,523 ÷ 2 = 62,537,261.5
If the quotient is a whole number, then 2 and 62,537,261.5 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 | 125,074,523 | |
| -1 | -125,074,523 |
Now, we try dividing 125,074,523 by 3:
125,074,523 ÷ 3 = 41,691,507.6667
If the quotient is a whole number, then 3 and 41,691,507.6667 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 | 125,074,523 | |
| -1 | -125,074,523 |
Let's try dividing by 4:
125,074,523 ÷ 4 = 31,268,630.75
If the quotient is a whole number, then 4 and 31,268,630.75 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 | 125,074,523 | |
| -1 | 125,074,523 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 359 | 497 | 701 | 2,513 | 4,907 | 25,489 | 49,771 | 178,423 | 251,659 | 348,397 | 1,761,613 | 17,867,789 | 125,074,523 |
| -1 | -7 | -71 | -359 | -497 | -701 | -2,513 | -4,907 | -25,489 | -49,771 | -178,423 | -251,659 | -348,397 | -1,761,613 | -17,867,789 | -125,074,523 |
