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 424,430,125, 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 | 424,430,125 | |
| -1 | -424,430,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 424,430,125.
Example:
1 x 424,430,125 = 424,430,125
and
-1 x -424,430,125 = 424,430,125
Notice both answers equal 424,430,125
With that explanation out of the way, let's continue. Next, we take the number 424,430,125 and divide it by 2:
424,430,125 ÷ 2 = 212,215,062.5
If the quotient is a whole number, then 2 and 212,215,062.5 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 | 424,430,125 | |
| -1 | -424,430,125 |
Now, we try dividing 424,430,125 by 3:
424,430,125 ÷ 3 = 141,476,708.3333
If the quotient is a whole number, then 3 and 141,476,708.3333 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 | 424,430,125 | |
| -1 | -424,430,125 |
Let's try dividing by 4:
424,430,125 ÷ 4 = 106,107,531.25
If the quotient is a whole number, then 4 and 106,107,531.25 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 | 424,430,125 | |
| -1 | 424,430,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 485,063 | 2,425,315 | 3,395,441 | 12,126,575 | 16,977,205 | 60,632,875 | 84,886,025 | 424,430,125 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -485,063 | -2,425,315 | -3,395,441 | -12,126,575 | -16,977,205 | -60,632,875 | -84,886,025 | -424,430,125 |
