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 141,251,131, 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 | 141,251,131 | |
| -1 | -141,251,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,251,131.
Example:
1 x 141,251,131 = 141,251,131
and
-1 x -141,251,131 = 141,251,131
Notice both answers equal 141,251,131
With that explanation out of the way, let's continue. Next, we take the number 141,251,131 and divide it by 2:
141,251,131 ÷ 2 = 70,625,565.5
If the quotient is a whole number, then 2 and 70,625,565.5 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 | 141,251,131 | |
| -1 | -141,251,131 |
Now, we try dividing 141,251,131 by 3:
141,251,131 ÷ 3 = 47,083,710.3333
If the quotient is a whole number, then 3 and 47,083,710.3333 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 | 141,251,131 | |
| -1 | -141,251,131 |
Let's try dividing by 4:
141,251,131 ÷ 4 = 35,312,782.75
If the quotient is a whole number, then 4 and 35,312,782.75 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 | 141,251,131 | |
| -1 | 141,251,131 |
If you did it right, you will end up with this table:
| 1 | 7 | 73 | 79 | 511 | 553 | 3,499 | 5,767 | 24,493 | 40,369 | 255,427 | 276,421 | 1,787,989 | 1,934,947 | 20,178,733 | 141,251,131 |
| -1 | -7 | -73 | -79 | -511 | -553 | -3,499 | -5,767 | -24,493 | -40,369 | -255,427 | -276,421 | -1,787,989 | -1,934,947 | -20,178,733 | -141,251,131 |
