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 2,054,525, 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 | 2,054,525 | |
| -1 | -2,054,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,054,525.
Example:
1 x 2,054,525 = 2,054,525
and
-1 x -2,054,525 = 2,054,525
Notice both answers equal 2,054,525
With that explanation out of the way, let's continue. Next, we take the number 2,054,525 and divide it by 2:
2,054,525 ÷ 2 = 1,027,262.5
If the quotient is a whole number, then 2 and 1,027,262.5 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 | 2,054,525 | |
| -1 | -2,054,525 |
Now, we try dividing 2,054,525 by 3:
2,054,525 ÷ 3 = 684,841.6667
If the quotient is a whole number, then 3 and 684,841.6667 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 | 2,054,525 | |
| -1 | -2,054,525 |
Let's try dividing by 4:
2,054,525 ÷ 4 = 513,631.25
If the quotient is a whole number, then 4 and 513,631.25 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 | 2,054,525 | |
| -1 | 2,054,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 31 | 55 | 155 | 241 | 275 | 341 | 775 | 1,205 | 1,705 | 2,651 | 6,025 | 7,471 | 8,525 | 13,255 | 37,355 | 66,275 | 82,181 | 186,775 | 410,905 | 2,054,525 |
| -1 | -5 | -11 | -25 | -31 | -55 | -155 | -241 | -275 | -341 | -775 | -1,205 | -1,705 | -2,651 | -6,025 | -7,471 | -8,525 | -13,255 | -37,355 | -66,275 | -82,181 | -186,775 | -410,905 | -2,054,525 |
