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 40,827,835, 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 | 40,827,835 | |
| -1 | -40,827,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,827,835.
Example:
1 x 40,827,835 = 40,827,835
and
-1 x -40,827,835 = 40,827,835
Notice both answers equal 40,827,835
With that explanation out of the way, let's continue. Next, we take the number 40,827,835 and divide it by 2:
40,827,835 ÷ 2 = 20,413,917.5
If the quotient is a whole number, then 2 and 20,413,917.5 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 | 40,827,835 | |
| -1 | -40,827,835 |
Now, we try dividing 40,827,835 by 3:
40,827,835 ÷ 3 = 13,609,278.3333
If the quotient is a whole number, then 3 and 13,609,278.3333 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 | 40,827,835 | |
| -1 | -40,827,835 |
Let's try dividing by 4:
40,827,835 ÷ 4 = 10,206,958.75
If the quotient is a whole number, then 4 and 10,206,958.75 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 | 40,827,835 | |
| -1 | 40,827,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 199 | 995 | 1,109 | 5,545 | 7,363 | 36,815 | 41,033 | 205,165 | 220,691 | 1,103,455 | 8,165,567 | 40,827,835 |
| -1 | -5 | -37 | -185 | -199 | -995 | -1,109 | -5,545 | -7,363 | -36,815 | -41,033 | -205,165 | -220,691 | -1,103,455 | -8,165,567 | -40,827,835 |
