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 140,034,713, 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 | 140,034,713 | |
| -1 | -140,034,713 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,034,713.
Example:
1 x 140,034,713 = 140,034,713
and
-1 x -140,034,713 = 140,034,713
Notice both answers equal 140,034,713
With that explanation out of the way, let's continue. Next, we take the number 140,034,713 and divide it by 2:
140,034,713 ÷ 2 = 70,017,356.5
If the quotient is a whole number, then 2 and 70,017,356.5 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 | 140,034,713 | |
| -1 | -140,034,713 |
Now, we try dividing 140,034,713 by 3:
140,034,713 ÷ 3 = 46,678,237.6667
If the quotient is a whole number, then 3 and 46,678,237.6667 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 | 140,034,713 | |
| -1 | -140,034,713 |
Let's try dividing by 4:
140,034,713 ÷ 4 = 35,008,678.25
If the quotient is a whole number, then 4 and 35,008,678.25 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 | 140,034,713 | |
| -1 | 140,034,713 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 1,181 | 1,303 | 8,267 | 9,121 | 15,353 | 16,939 | 107,471 | 118,573 | 1,538,843 | 10,771,901 | 20,004,959 | 140,034,713 |
| -1 | -7 | -13 | -91 | -1,181 | -1,303 | -8,267 | -9,121 | -15,353 | -16,939 | -107,471 | -118,573 | -1,538,843 | -10,771,901 | -20,004,959 | -140,034,713 |
