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 2,641,475, 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 | 2,641,475 | |
| -1 | -2,641,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,641,475.
Example:
1 x 2,641,475 = 2,641,475
and
-1 x -2,641,475 = 2,641,475
Notice both answers equal 2,641,475
With that explanation out of the way, let's continue. Next, we take the number 2,641,475 and divide it by 2:
2,641,475 ÷ 2 = 1,320,737.5
If the quotient is a whole number, then 2 and 1,320,737.5 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 | 2,641,475 | |
| -1 | -2,641,475 |
Now, we try dividing 2,641,475 by 3:
2,641,475 ÷ 3 = 880,491.6667
If the quotient is a whole number, then 3 and 880,491.6667 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 | 2,641,475 | |
| -1 | -2,641,475 |
Let's try dividing by 4:
2,641,475 ÷ 4 = 660,368.75
If the quotient is a whole number, then 4 and 660,368.75 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 | 2,641,475 | |
| -1 | 2,641,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 67 | 83 | 95 | 335 | 415 | 475 | 1,273 | 1,577 | 1,675 | 2,075 | 5,561 | 6,365 | 7,885 | 27,805 | 31,825 | 39,425 | 105,659 | 139,025 | 528,295 | 2,641,475 |
| -1 | -5 | -19 | -25 | -67 | -83 | -95 | -335 | -415 | -475 | -1,273 | -1,577 | -1,675 | -2,075 | -5,561 | -6,365 | -7,885 | -27,805 | -31,825 | -39,425 | -105,659 | -139,025 | -528,295 | -2,641,475 |
