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 2,490,475, 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 | 2,490,475 | |
| -1 | -2,490,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,490,475.
Example:
1 x 2,490,475 = 2,490,475
and
-1 x -2,490,475 = 2,490,475
Notice both answers equal 2,490,475
With that explanation out of the way, let's continue. Next, we take the number 2,490,475 and divide it by 2:
2,490,475 ÷ 2 = 1,245,237.5
If the quotient is a whole number, then 2 and 1,245,237.5 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 | 2,490,475 | |
| -1 | -2,490,475 |
Now, we try dividing 2,490,475 by 3:
2,490,475 ÷ 3 = 830,158.3333
If the quotient is a whole number, then 3 and 830,158.3333 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 | 2,490,475 | |
| -1 | -2,490,475 |
Let's try dividing by 4:
2,490,475 ÷ 4 = 622,618.75
If the quotient is a whole number, then 4 and 622,618.75 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 | 2,490,475 | |
| -1 | 2,490,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 79 | 97 | 325 | 395 | 485 | 1,027 | 1,261 | 1,975 | 2,425 | 5,135 | 6,305 | 7,663 | 25,675 | 31,525 | 38,315 | 99,619 | 191,575 | 498,095 | 2,490,475 |
| -1 | -5 | -13 | -25 | -65 | -79 | -97 | -325 | -395 | -485 | -1,027 | -1,261 | -1,975 | -2,425 | -5,135 | -6,305 | -7,663 | -25,675 | -31,525 | -38,315 | -99,619 | -191,575 | -498,095 | -2,490,475 |
