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 457,425,667, 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 | 457,425,667 | |
| -1 | -457,425,667 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 457,425,667.
Example:
1 x 457,425,667 = 457,425,667
and
-1 x -457,425,667 = 457,425,667
Notice both answers equal 457,425,667
With that explanation out of the way, let's continue. Next, we take the number 457,425,667 and divide it by 2:
457,425,667 ÷ 2 = 228,712,833.5
If the quotient is a whole number, then 2 and 228,712,833.5 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 | 457,425,667 | |
| -1 | -457,425,667 |
Now, we try dividing 457,425,667 by 3:
457,425,667 ÷ 3 = 152,475,222.3333
If the quotient is a whole number, then 3 and 152,475,222.3333 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 | 457,425,667 | |
| -1 | -457,425,667 |
Let's try dividing by 4:
457,425,667 ÷ 4 = 114,356,416.75
If the quotient is a whole number, then 4 and 114,356,416.75 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 | 457,425,667 | |
| -1 | 457,425,667 |
If you did it right, you will end up with this table:
| 1 | 47 | 101 | 173 | 557 | 4,747 | 8,131 | 17,473 | 26,179 | 56,257 | 96,361 | 821,231 | 2,644,079 | 4,528,967 | 9,732,461 | 457,425,667 |
| -1 | -47 | -101 | -173 | -557 | -4,747 | -8,131 | -17,473 | -26,179 | -56,257 | -96,361 | -821,231 | -2,644,079 | -4,528,967 | -9,732,461 | -457,425,667 |
