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 141,356,761, 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 | 141,356,761 | |
| -1 | -141,356,761 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,356,761.
Example:
1 x 141,356,761 = 141,356,761
and
-1 x -141,356,761 = 141,356,761
Notice both answers equal 141,356,761
With that explanation out of the way, let's continue. Next, we take the number 141,356,761 and divide it by 2:
141,356,761 ÷ 2 = 70,678,380.5
If the quotient is a whole number, then 2 and 70,678,380.5 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 | 141,356,761 | |
| -1 | -141,356,761 |
Now, we try dividing 141,356,761 by 3:
141,356,761 ÷ 3 = 47,118,920.3333
If the quotient is a whole number, then 3 and 47,118,920.3333 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 | 141,356,761 | |
| -1 | -141,356,761 |
Let's try dividing by 4:
141,356,761 ÷ 4 = 35,339,190.25
If the quotient is a whole number, then 4 and 35,339,190.25 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 | 141,356,761 | |
| -1 | 141,356,761 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 37 | 91 | 259 | 481 | 3,367 | 41,983 | 293,881 | 545,779 | 1,553,371 | 3,820,453 | 10,873,597 | 20,193,823 | 141,356,761 |
| -1 | -7 | -13 | -37 | -91 | -259 | -481 | -3,367 | -41,983 | -293,881 | -545,779 | -1,553,371 | -3,820,453 | -10,873,597 | -20,193,823 | -141,356,761 |
