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 143,355,407, 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 | 143,355,407 | |
| -1 | -143,355,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,355,407.
Example:
1 x 143,355,407 = 143,355,407
and
-1 x -143,355,407 = 143,355,407
Notice both answers equal 143,355,407
With that explanation out of the way, let's continue. Next, we take the number 143,355,407 and divide it by 2:
143,355,407 ÷ 2 = 71,677,703.5
If the quotient is a whole number, then 2 and 71,677,703.5 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 | 143,355,407 | |
| -1 | -143,355,407 |
Now, we try dividing 143,355,407 by 3:
143,355,407 ÷ 3 = 47,785,135.6667
If the quotient is a whole number, then 3 and 47,785,135.6667 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 | 143,355,407 | |
| -1 | -143,355,407 |
Let's try dividing by 4:
143,355,407 ÷ 4 = 35,838,851.75
If the quotient is a whole number, then 4 and 35,838,851.75 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 | 143,355,407 | |
| -1 | 143,355,407 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 53 | 221 | 689 | 901 | 11,713 | 12,239 | 159,107 | 208,063 | 648,667 | 2,704,819 | 8,432,671 | 11,027,339 | 143,355,407 |
| -1 | -13 | -17 | -53 | -221 | -689 | -901 | -11,713 | -12,239 | -159,107 | -208,063 | -648,667 | -2,704,819 | -8,432,671 | -11,027,339 | -143,355,407 |
