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 143,342,011, 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 | 143,342,011 | |
| -1 | -143,342,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,342,011.
Example:
1 x 143,342,011 = 143,342,011
and
-1 x -143,342,011 = 143,342,011
Notice both answers equal 143,342,011
With that explanation out of the way, let's continue. Next, we take the number 143,342,011 and divide it by 2:
143,342,011 ÷ 2 = 71,671,005.5
If the quotient is a whole number, then 2 and 71,671,005.5 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 | 143,342,011 | |
| -1 | -143,342,011 |
Now, we try dividing 143,342,011 by 3:
143,342,011 ÷ 3 = 47,780,670.3333
If the quotient is a whole number, then 3 and 47,780,670.3333 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 | 143,342,011 | |
| -1 | -143,342,011 |
Let's try dividing by 4:
143,342,011 ÷ 4 = 35,835,502.75
If the quotient is a whole number, then 4 and 35,835,502.75 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 | 143,342,011 | |
| -1 | 143,342,011 |
If you did it right, you will end up with this table:
| 1 | 17 | 67 | 317 | 397 | 1,139 | 5,389 | 6,749 | 21,239 | 26,599 | 125,849 | 361,063 | 452,183 | 2,139,433 | 8,431,883 | 143,342,011 |
| -1 | -17 | -67 | -317 | -397 | -1,139 | -5,389 | -6,749 | -21,239 | -26,599 | -125,849 | -361,063 | -452,183 | -2,139,433 | -8,431,883 | -143,342,011 |
