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 40,103,855, 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 | 40,103,855 | |
| -1 | -40,103,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,103,855.
Example:
1 x 40,103,855 = 40,103,855
and
-1 x -40,103,855 = 40,103,855
Notice both answers equal 40,103,855
With that explanation out of the way, let's continue. Next, we take the number 40,103,855 and divide it by 2:
40,103,855 ÷ 2 = 20,051,927.5
If the quotient is a whole number, then 2 and 20,051,927.5 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 | 40,103,855 | |
| -1 | -40,103,855 |
Now, we try dividing 40,103,855 by 3:
40,103,855 ÷ 3 = 13,367,951.6667
If the quotient is a whole number, then 3 and 13,367,951.6667 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 | 40,103,855 | |
| -1 | -40,103,855 |
Let's try dividing by 4:
40,103,855 ÷ 4 = 10,025,963.75
If the quotient is a whole number, then 4 and 10,025,963.75 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 | 40,103,855 | |
| -1 | 40,103,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 67 | 335 | 737 | 3,685 | 10,883 | 54,415 | 119,713 | 598,565 | 729,161 | 3,645,805 | 8,020,771 | 40,103,855 |
| -1 | -5 | -11 | -55 | -67 | -335 | -737 | -3,685 | -10,883 | -54,415 | -119,713 | -598,565 | -729,161 | -3,645,805 | -8,020,771 | -40,103,855 |
