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 140,114,221, 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 | 140,114,221 | |
| -1 | -140,114,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,114,221.
Example:
1 x 140,114,221 = 140,114,221
and
-1 x -140,114,221 = 140,114,221
Notice both answers equal 140,114,221
With that explanation out of the way, let's continue. Next, we take the number 140,114,221 and divide it by 2:
140,114,221 ÷ 2 = 70,057,110.5
If the quotient is a whole number, then 2 and 70,057,110.5 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 | 140,114,221 | |
| -1 | -140,114,221 |
Now, we try dividing 140,114,221 by 3:
140,114,221 ÷ 3 = 46,704,740.3333
If the quotient is a whole number, then 3 and 46,704,740.3333 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 | 140,114,221 | |
| -1 | -140,114,221 |
Let's try dividing by 4:
140,114,221 ÷ 4 = 35,028,555.25
If the quotient is a whole number, then 4 and 35,028,555.25 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 | 140,114,221 | |
| -1 | 140,114,221 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 431 | 1,471 | 5,603 | 7,327 | 19,123 | 25,007 | 95,251 | 325,091 | 634,001 | 8,242,013 | 10,778,017 | 140,114,221 |
| -1 | -13 | -17 | -221 | -431 | -1,471 | -5,603 | -7,327 | -19,123 | -25,007 | -95,251 | -325,091 | -634,001 | -8,242,013 | -10,778,017 | -140,114,221 |
