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 40,944,025, 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 | 40,944,025 | |
| -1 | -40,944,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,944,025.
Example:
1 x 40,944,025 = 40,944,025
and
-1 x -40,944,025 = 40,944,025
Notice both answers equal 40,944,025
With that explanation out of the way, let's continue. Next, we take the number 40,944,025 and divide it by 2:
40,944,025 ÷ 2 = 20,472,012.5
If the quotient is a whole number, then 2 and 20,472,012.5 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 | 40,944,025 | |
| -1 | -40,944,025 |
Now, we try dividing 40,944,025 by 3:
40,944,025 ÷ 3 = 13,648,008.3333
If the quotient is a whole number, then 3 and 13,648,008.3333 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 | 40,944,025 | |
| -1 | -40,944,025 |
Let's try dividing by 4:
40,944,025 ÷ 4 = 10,236,006.25
If the quotient is a whole number, then 4 and 10,236,006.25 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 | 40,944,025 | |
| -1 | 40,944,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 31 | 115 | 155 | 575 | 713 | 775 | 2,297 | 3,565 | 11,485 | 17,825 | 52,831 | 57,425 | 71,207 | 264,155 | 356,035 | 1,320,775 | 1,637,761 | 1,780,175 | 8,188,805 | 40,944,025 |
| -1 | -5 | -23 | -25 | -31 | -115 | -155 | -575 | -713 | -775 | -2,297 | -3,565 | -11,485 | -17,825 | -52,831 | -57,425 | -71,207 | -264,155 | -356,035 | -1,320,775 | -1,637,761 | -1,780,175 | -8,188,805 | -40,944,025 |
