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 143,312,137, 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 | 143,312,137 | |
| -1 | -143,312,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,312,137.
Example:
1 x 143,312,137 = 143,312,137
and
-1 x -143,312,137 = 143,312,137
Notice both answers equal 143,312,137
With that explanation out of the way, let's continue. Next, we take the number 143,312,137 and divide it by 2:
143,312,137 ÷ 2 = 71,656,068.5
If the quotient is a whole number, then 2 and 71,656,068.5 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 | 143,312,137 | |
| -1 | -143,312,137 |
Now, we try dividing 143,312,137 by 3:
143,312,137 ÷ 3 = 47,770,712.3333
If the quotient is a whole number, then 3 and 47,770,712.3333 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 | 143,312,137 | |
| -1 | -143,312,137 |
Let's try dividing by 4:
143,312,137 ÷ 4 = 35,828,034.25
If the quotient is a whole number, then 4 and 35,828,034.25 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 | 143,312,137 | |
| -1 | 143,312,137 |
If you did it right, you will end up with this table:
| 1 | 37 | 113 | 151 | 227 | 4,181 | 5,587 | 8,399 | 17,063 | 25,651 | 34,277 | 631,331 | 949,087 | 1,268,249 | 3,873,301 | 143,312,137 |
| -1 | -37 | -113 | -151 | -227 | -4,181 | -5,587 | -8,399 | -17,063 | -25,651 | -34,277 | -631,331 | -949,087 | -1,268,249 | -3,873,301 | -143,312,137 |
