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 434,040,425, 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 | 434,040,425 | |
| -1 | -434,040,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 434,040,425.
Example:
1 x 434,040,425 = 434,040,425
and
-1 x -434,040,425 = 434,040,425
Notice both answers equal 434,040,425
With that explanation out of the way, let's continue. Next, we take the number 434,040,425 and divide it by 2:
434,040,425 ÷ 2 = 217,020,212.5
If the quotient is a whole number, then 2 and 217,020,212.5 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 | 434,040,425 | |
| -1 | -434,040,425 |
Now, we try dividing 434,040,425 by 3:
434,040,425 ÷ 3 = 144,680,141.6667
If the quotient is a whole number, then 3 and 144,680,141.6667 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 | 434,040,425 | |
| -1 | -434,040,425 |
Let's try dividing by 4:
434,040,425 ÷ 4 = 108,510,106.25
If the quotient is a whole number, then 4 and 108,510,106.25 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 | 434,040,425 | |
| -1 | 434,040,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 325 | 455 | 2,275 | 190,787 | 953,935 | 1,335,509 | 2,480,231 | 4,769,675 | 6,677,545 | 12,401,155 | 17,361,617 | 33,387,725 | 62,005,775 | 86,808,085 | 434,040,425 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -325 | -455 | -2,275 | -190,787 | -953,935 | -1,335,509 | -2,480,231 | -4,769,675 | -6,677,545 | -12,401,155 | -17,361,617 | -33,387,725 | -62,005,775 | -86,808,085 | -434,040,425 |
