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 140,834,783, 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 | 140,834,783 | |
| -1 | -140,834,783 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,834,783.
Example:
1 x 140,834,783 = 140,834,783
and
-1 x -140,834,783 = 140,834,783
Notice both answers equal 140,834,783
With that explanation out of the way, let's continue. Next, we take the number 140,834,783 and divide it by 2:
140,834,783 ÷ 2 = 70,417,391.5
If the quotient is a whole number, then 2 and 70,417,391.5 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 | 140,834,783 | |
| -1 | -140,834,783 |
Now, we try dividing 140,834,783 by 3:
140,834,783 ÷ 3 = 46,944,927.6667
If the quotient is a whole number, then 3 and 46,944,927.6667 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 | 140,834,783 | |
| -1 | -140,834,783 |
Let's try dividing by 4:
140,834,783 ÷ 4 = 35,208,695.75
If the quotient is a whole number, then 4 and 35,208,695.75 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 | 140,834,783 | |
| -1 | 140,834,783 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 323 | 631 | 691 | 10,727 | 11,747 | 11,989 | 13,129 | 203,813 | 223,193 | 436,021 | 7,412,357 | 8,284,399 | 140,834,783 |
| -1 | -17 | -19 | -323 | -631 | -691 | -10,727 | -11,747 | -11,989 | -13,129 | -203,813 | -223,193 | -436,021 | -7,412,357 | -8,284,399 | -140,834,783 |
