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 143,743,379, 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 | 143,743,379 | |
| -1 | -143,743,379 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,743,379.
Example:
1 x 143,743,379 = 143,743,379
and
-1 x -143,743,379 = 143,743,379
Notice both answers equal 143,743,379
With that explanation out of the way, let's continue. Next, we take the number 143,743,379 and divide it by 2:
143,743,379 ÷ 2 = 71,871,689.5
If the quotient is a whole number, then 2 and 71,871,689.5 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 | 143,743,379 | |
| -1 | -143,743,379 |
Now, we try dividing 143,743,379 by 3:
143,743,379 ÷ 3 = 47,914,459.6667
If the quotient is a whole number, then 3 and 47,914,459.6667 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 | 143,743,379 | |
| -1 | -143,743,379 |
Let's try dividing by 4:
143,743,379 ÷ 4 = 35,935,844.75
If the quotient is a whole number, then 4 and 35,935,844.75 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 | 143,743,379 | |
| -1 | 143,743,379 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 247 | 521 | 1,117 | 6,773 | 9,899 | 14,521 | 21,223 | 128,687 | 275,899 | 581,957 | 7,565,441 | 11,057,183 | 143,743,379 |
| -1 | -13 | -19 | -247 | -521 | -1,117 | -6,773 | -9,899 | -14,521 | -21,223 | -128,687 | -275,899 | -581,957 | -7,565,441 | -11,057,183 | -143,743,379 |
