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 143,311,025, 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 | 143,311,025 | |
| -1 | -143,311,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,311,025.
Example:
1 x 143,311,025 = 143,311,025
and
-1 x -143,311,025 = 143,311,025
Notice both answers equal 143,311,025
With that explanation out of the way, let's continue. Next, we take the number 143,311,025 and divide it by 2:
143,311,025 ÷ 2 = 71,655,512.5
If the quotient is a whole number, then 2 and 71,655,512.5 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 | 143,311,025 | |
| -1 | -143,311,025 |
Now, we try dividing 143,311,025 by 3:
143,311,025 ÷ 3 = 47,770,341.6667
If the quotient is a whole number, then 3 and 47,770,341.6667 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 | 143,311,025 | |
| -1 | -143,311,025 |
Let's try dividing by 4:
143,311,025 ÷ 4 = 35,827,756.25
If the quotient is a whole number, then 4 and 35,827,756.25 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 | 143,311,025 | |
| -1 | 143,311,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 143 | 275 | 325 | 715 | 3,575 | 40,087 | 200,435 | 440,957 | 521,131 | 1,002,175 | 2,204,785 | 2,605,655 | 5,732,441 | 11,023,925 | 13,028,275 | 28,662,205 | 143,311,025 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -143 | -275 | -325 | -715 | -3,575 | -40,087 | -200,435 | -440,957 | -521,131 | -1,002,175 | -2,204,785 | -2,605,655 | -5,732,441 | -11,023,925 | -13,028,275 | -28,662,205 | -143,311,025 |
