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 40,732,355, 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 | 40,732,355 | |
| -1 | -40,732,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,732,355.
Example:
1 x 40,732,355 = 40,732,355
and
-1 x -40,732,355 = 40,732,355
Notice both answers equal 40,732,355
With that explanation out of the way, let's continue. Next, we take the number 40,732,355 and divide it by 2:
40,732,355 ÷ 2 = 20,366,177.5
If the quotient is a whole number, then 2 and 20,366,177.5 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 | 40,732,355 | |
| -1 | -40,732,355 |
Now, we try dividing 40,732,355 by 3:
40,732,355 ÷ 3 = 13,577,451.6667
If the quotient is a whole number, then 3 and 13,577,451.6667 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 | 40,732,355 | |
| -1 | -40,732,355 |
Let's try dividing by 4:
40,732,355 ÷ 4 = 10,183,088.75
If the quotient is a whole number, then 4 and 10,183,088.75 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 | 40,732,355 | |
| -1 | 40,732,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 265 | 281 | 547 | 1,405 | 2,735 | 14,893 | 28,991 | 74,465 | 144,955 | 153,707 | 768,535 | 8,146,471 | 40,732,355 |
| -1 | -5 | -53 | -265 | -281 | -547 | -1,405 | -2,735 | -14,893 | -28,991 | -74,465 | -144,955 | -153,707 | -768,535 | -8,146,471 | -40,732,355 |
