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 141,653,837, 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 | 141,653,837 | |
| -1 | -141,653,837 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,653,837.
Example:
1 x 141,653,837 = 141,653,837
and
-1 x -141,653,837 = 141,653,837
Notice both answers equal 141,653,837
With that explanation out of the way, let's continue. Next, we take the number 141,653,837 and divide it by 2:
141,653,837 ÷ 2 = 70,826,918.5
If the quotient is a whole number, then 2 and 70,826,918.5 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 | 141,653,837 | |
| -1 | -141,653,837 |
Now, we try dividing 141,653,837 by 3:
141,653,837 ÷ 3 = 47,217,945.6667
If the quotient is a whole number, then 3 and 47,217,945.6667 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 | 141,653,837 | |
| -1 | -141,653,837 |
Let's try dividing by 4:
141,653,837 ÷ 4 = 35,413,459.25
If the quotient is a whole number, then 4 and 35,413,459.25 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 | 141,653,837 | |
| -1 | 141,653,837 |
If you did it right, you will end up with this table:
| 1 | 13 | 131 | 223 | 373 | 1,703 | 2,899 | 4,849 | 29,213 | 48,863 | 83,179 | 379,769 | 635,219 | 1,081,327 | 10,896,449 | 141,653,837 |
| -1 | -13 | -131 | -223 | -373 | -1,703 | -2,899 | -4,849 | -29,213 | -48,863 | -83,179 | -379,769 | -635,219 | -1,081,327 | -10,896,449 | -141,653,837 |
