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 140,607,629, 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 | 140,607,629 | |
| -1 | -140,607,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,607,629.
Example:
1 x 140,607,629 = 140,607,629
and
-1 x -140,607,629 = 140,607,629
Notice both answers equal 140,607,629
With that explanation out of the way, let's continue. Next, we take the number 140,607,629 and divide it by 2:
140,607,629 ÷ 2 = 70,303,814.5
If the quotient is a whole number, then 2 and 70,303,814.5 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 | 140,607,629 | |
| -1 | -140,607,629 |
Now, we try dividing 140,607,629 by 3:
140,607,629 ÷ 3 = 46,869,209.6667
If the quotient is a whole number, then 3 and 46,869,209.6667 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 | 140,607,629 | |
| -1 | -140,607,629 |
Let's try dividing by 4:
140,607,629 ÷ 4 = 35,151,907.25
If the quotient is a whole number, then 4 and 35,151,907.25 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 | 140,607,629 | |
| -1 | 140,607,629 |
If you did it right, you will end up with this table:
| 1 | 17 | 89 | 199 | 467 | 1,513 | 3,383 | 7,939 | 17,711 | 41,563 | 92,933 | 301,087 | 706,571 | 1,579,861 | 8,271,037 | 140,607,629 |
| -1 | -17 | -89 | -199 | -467 | -1,513 | -3,383 | -7,939 | -17,711 | -41,563 | -92,933 | -301,087 | -706,571 | -1,579,861 | -8,271,037 | -140,607,629 |
