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 143,265,137, 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 | 143,265,137 | |
| -1 | -143,265,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,265,137.
Example:
1 x 143,265,137 = 143,265,137
and
-1 x -143,265,137 = 143,265,137
Notice both answers equal 143,265,137
With that explanation out of the way, let's continue. Next, we take the number 143,265,137 and divide it by 2:
143,265,137 ÷ 2 = 71,632,568.5
If the quotient is a whole number, then 2 and 71,632,568.5 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 | 143,265,137 | |
| -1 | -143,265,137 |
Now, we try dividing 143,265,137 by 3:
143,265,137 ÷ 3 = 47,755,045.6667
If the quotient is a whole number, then 3 and 47,755,045.6667 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 | 143,265,137 | |
| -1 | -143,265,137 |
Let's try dividing by 4:
143,265,137 ÷ 4 = 35,816,284.25
If the quotient is a whole number, then 4 and 35,816,284.25 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 | 143,265,137 | |
| -1 | 143,265,137 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 131 | 391 | 2,227 | 2,797 | 3,013 | 47,549 | 51,221 | 64,331 | 366,407 | 1,093,627 | 6,228,919 | 8,427,361 | 143,265,137 |
| -1 | -17 | -23 | -131 | -391 | -2,227 | -2,797 | -3,013 | -47,549 | -51,221 | -64,331 | -366,407 | -1,093,627 | -6,228,919 | -8,427,361 | -143,265,137 |
