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 40,034,845, 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 | 40,034,845 | |
| -1 | -40,034,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,034,845.
Example:
1 x 40,034,845 = 40,034,845
and
-1 x -40,034,845 = 40,034,845
Notice both answers equal 40,034,845
With that explanation out of the way, let's continue. Next, we take the number 40,034,845 and divide it by 2:
40,034,845 ÷ 2 = 20,017,422.5
If the quotient is a whole number, then 2 and 20,017,422.5 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 | 40,034,845 | |
| -1 | -40,034,845 |
Now, we try dividing 40,034,845 by 3:
40,034,845 ÷ 3 = 13,344,948.3333
If the quotient is a whole number, then 3 and 13,344,948.3333 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 | 40,034,845 | |
| -1 | -40,034,845 |
Let's try dividing by 4:
40,034,845 ÷ 4 = 10,008,711.25
If the quotient is a whole number, then 4 and 10,008,711.25 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 | 40,034,845 | |
| -1 | 40,034,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 127 | 335 | 635 | 941 | 4,705 | 8,509 | 42,545 | 63,047 | 119,507 | 315,235 | 597,535 | 8,006,969 | 40,034,845 |
| -1 | -5 | -67 | -127 | -335 | -635 | -941 | -4,705 | -8,509 | -42,545 | -63,047 | -119,507 | -315,235 | -597,535 | -8,006,969 | -40,034,845 |
