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 140,333,435, 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 | 140,333,435 | |
| -1 | -140,333,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,333,435.
Example:
1 x 140,333,435 = 140,333,435
and
-1 x -140,333,435 = 140,333,435
Notice both answers equal 140,333,435
With that explanation out of the way, let's continue. Next, we take the number 140,333,435 and divide it by 2:
140,333,435 ÷ 2 = 70,166,717.5
If the quotient is a whole number, then 2 and 70,166,717.5 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 | 140,333,435 | |
| -1 | -140,333,435 |
Now, we try dividing 140,333,435 by 3:
140,333,435 ÷ 3 = 46,777,811.6667
If the quotient is a whole number, then 3 and 46,777,811.6667 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 | 140,333,435 | |
| -1 | -140,333,435 |
Let's try dividing by 4:
140,333,435 ÷ 4 = 35,083,358.75
If the quotient is a whole number, then 4 and 35,083,358.75 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 | 140,333,435 | |
| -1 | 140,333,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 155 | 341 | 1,705 | 82,307 | 411,535 | 905,377 | 2,551,517 | 4,526,885 | 12,757,585 | 28,066,687 | 140,333,435 |
| -1 | -5 | -11 | -31 | -55 | -155 | -341 | -1,705 | -82,307 | -411,535 | -905,377 | -2,551,517 | -4,526,885 | -12,757,585 | -28,066,687 | -140,333,435 |
