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 1,377,425, 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 | 1,377,425 | |
| -1 | -1,377,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,377,425.
Example:
1 x 1,377,425 = 1,377,425
and
-1 x -1,377,425 = 1,377,425
Notice both answers equal 1,377,425
With that explanation out of the way, let's continue. Next, we take the number 1,377,425 and divide it by 2:
1,377,425 ÷ 2 = 688,712.5
If the quotient is a whole number, then 2 and 688,712.5 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 | 1,377,425 | |
| -1 | -1,377,425 |
Now, we try dividing 1,377,425 by 3:
1,377,425 ÷ 3 = 459,141.6667
If the quotient is a whole number, then 3 and 459,141.6667 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 | 1,377,425 | |
| -1 | -1,377,425 |
Let's try dividing by 4:
1,377,425 ÷ 4 = 344,356.25
If the quotient is a whole number, then 4 and 344,356.25 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 | 1,377,425 | |
| -1 | 1,377,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 25 | 35 | 85 | 119 | 175 | 425 | 463 | 595 | 2,315 | 2,975 | 3,241 | 7,871 | 11,575 | 16,205 | 39,355 | 55,097 | 81,025 | 196,775 | 275,485 | 1,377,425 |
| -1 | -5 | -7 | -17 | -25 | -35 | -85 | -119 | -175 | -425 | -463 | -595 | -2,315 | -2,975 | -3,241 | -7,871 | -11,575 | -16,205 | -39,355 | -55,097 | -81,025 | -196,775 | -275,485 | -1,377,425 |
