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 611,124,143, 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 | 611,124,143 | |
| -1 | -611,124,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 611,124,143.
Example:
1 x 611,124,143 = 611,124,143
and
-1 x -611,124,143 = 611,124,143
Notice both answers equal 611,124,143
With that explanation out of the way, let's continue. Next, we take the number 611,124,143 and divide it by 2:
611,124,143 ÷ 2 = 305,562,071.5
If the quotient is a whole number, then 2 and 305,562,071.5 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 | 611,124,143 | |
| -1 | -611,124,143 |
Now, we try dividing 611,124,143 by 3:
611,124,143 ÷ 3 = 203,708,047.6667
If the quotient is a whole number, then 3 and 203,708,047.6667 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 | 611,124,143 | |
| -1 | -611,124,143 |
Let's try dividing by 4:
611,124,143 ÷ 4 = 152,781,035.75
If the quotient is a whole number, then 4 and 152,781,035.75 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 | 611,124,143 | |
| -1 | 611,124,143 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 521 | 3,647 | 8,857 | 9,857 | 61,999 | 68,999 | 167,569 | 1,172,983 | 5,135,497 | 35,948,479 | 87,303,449 | 611,124,143 |
| -1 | -7 | -17 | -119 | -521 | -3,647 | -8,857 | -9,857 | -61,999 | -68,999 | -167,569 | -1,172,983 | -5,135,497 | -35,948,479 | -87,303,449 | -611,124,143 |
