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 2,440,475, 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 | 2,440,475 | |
| -1 | -2,440,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,440,475.
Example:
1 x 2,440,475 = 2,440,475
and
-1 x -2,440,475 = 2,440,475
Notice both answers equal 2,440,475
With that explanation out of the way, let's continue. Next, we take the number 2,440,475 and divide it by 2:
2,440,475 ÷ 2 = 1,220,237.5
If the quotient is a whole number, then 2 and 1,220,237.5 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 | 2,440,475 | |
| -1 | -2,440,475 |
Now, we try dividing 2,440,475 by 3:
2,440,475 ÷ 3 = 813,491.6667
If the quotient is a whole number, then 3 and 813,491.6667 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 | 2,440,475 | |
| -1 | -2,440,475 |
Let's try dividing by 4:
2,440,475 ÷ 4 = 610,118.75
If the quotient is a whole number, then 4 and 610,118.75 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 | 2,440,475 | |
| -1 | 2,440,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 47 | 67 | 155 | 235 | 335 | 775 | 1,175 | 1,457 | 1,675 | 2,077 | 3,149 | 7,285 | 10,385 | 15,745 | 36,425 | 51,925 | 78,725 | 97,619 | 488,095 | 2,440,475 |
| -1 | -5 | -25 | -31 | -47 | -67 | -155 | -235 | -335 | -775 | -1,175 | -1,457 | -1,675 | -2,077 | -3,149 | -7,285 | -10,385 | -15,745 | -36,425 | -51,925 | -78,725 | -97,619 | -488,095 | -2,440,475 |
