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 140,010,311, 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 | 140,010,311 | |
| -1 | -140,010,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,010,311.
Example:
1 x 140,010,311 = 140,010,311
and
-1 x -140,010,311 = 140,010,311
Notice both answers equal 140,010,311
With that explanation out of the way, let's continue. Next, we take the number 140,010,311 and divide it by 2:
140,010,311 ÷ 2 = 70,005,155.5
If the quotient is a whole number, then 2 and 70,005,155.5 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 | 140,010,311 | |
| -1 | -140,010,311 |
Now, we try dividing 140,010,311 by 3:
140,010,311 ÷ 3 = 46,670,103.6667
If the quotient is a whole number, then 3 and 46,670,103.6667 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 | 140,010,311 | |
| -1 | -140,010,311 |
Let's try dividing by 4:
140,010,311 ÷ 4 = 35,002,577.75
If the quotient is a whole number, then 4 and 35,002,577.75 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 | 140,010,311 | |
| -1 | 140,010,311 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 131 | 427 | 917 | 2,503 | 7,991 | 17,521 | 55,937 | 152,683 | 327,893 | 1,068,781 | 2,295,251 | 20,001,473 | 140,010,311 |
| -1 | -7 | -61 | -131 | -427 | -917 | -2,503 | -7,991 | -17,521 | -55,937 | -152,683 | -327,893 | -1,068,781 | -2,295,251 | -20,001,473 | -140,010,311 |
