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 141,446,261, 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 | 141,446,261 | |
| -1 | -141,446,261 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,446,261.
Example:
1 x 141,446,261 = 141,446,261
and
-1 x -141,446,261 = 141,446,261
Notice both answers equal 141,446,261
With that explanation out of the way, let's continue. Next, we take the number 141,446,261 and divide it by 2:
141,446,261 ÷ 2 = 70,723,130.5
If the quotient is a whole number, then 2 and 70,723,130.5 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 | 141,446,261 | |
| -1 | -141,446,261 |
Now, we try dividing 141,446,261 by 3:
141,446,261 ÷ 3 = 47,148,753.6667
If the quotient is a whole number, then 3 and 47,148,753.6667 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 | 141,446,261 | |
| -1 | -141,446,261 |
Let's try dividing by 4:
141,446,261 ÷ 4 = 35,361,565.25
If the quotient is a whole number, then 4 and 35,361,565.25 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 | 141,446,261 | |
| -1 | 141,446,261 |
If you did it right, you will end up with this table:
| 1 | 11 | 79 | 139 | 869 | 1,171 | 1,529 | 10,981 | 12,881 | 92,509 | 120,791 | 162,769 | 1,017,599 | 1,790,459 | 12,858,751 | 141,446,261 |
| -1 | -11 | -79 | -139 | -869 | -1,171 | -1,529 | -10,981 | -12,881 | -92,509 | -120,791 | -162,769 | -1,017,599 | -1,790,459 | -12,858,751 | -141,446,261 |
