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 451,623,425, 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 | 451,623,425 | |
| -1 | -451,623,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 451,623,425.
Example:
1 x 451,623,425 = 451,623,425
and
-1 x -451,623,425 = 451,623,425
Notice both answers equal 451,623,425
With that explanation out of the way, let's continue. Next, we take the number 451,623,425 and divide it by 2:
451,623,425 ÷ 2 = 225,811,712.5
If the quotient is a whole number, then 2 and 225,811,712.5 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 | 451,623,425 | |
| -1 | -451,623,425 |
Now, we try dividing 451,623,425 by 3:
451,623,425 ÷ 3 = 150,541,141.6667
If the quotient is a whole number, then 3 and 150,541,141.6667 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 | 451,623,425 | |
| -1 | -451,623,425 |
Let's try dividing by 4:
451,623,425 ÷ 4 = 112,905,856.25
If the quotient is a whole number, then 4 and 112,905,856.25 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 | 451,623,425 | |
| -1 | 451,623,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 605 | 3,025 | 149,297 | 746,485 | 1,642,267 | 3,732,425 | 8,211,335 | 18,064,937 | 41,056,675 | 90,324,685 | 451,623,425 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -605 | -3,025 | -149,297 | -746,485 | -1,642,267 | -3,732,425 | -8,211,335 | -18,064,937 | -41,056,675 | -90,324,685 | -451,623,425 |
