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 141,251,227, 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 | 141,251,227 | |
| -1 | -141,251,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,251,227.
Example:
1 x 141,251,227 = 141,251,227
and
-1 x -141,251,227 = 141,251,227
Notice both answers equal 141,251,227
With that explanation out of the way, let's continue. Next, we take the number 141,251,227 and divide it by 2:
141,251,227 ÷ 2 = 70,625,613.5
If the quotient is a whole number, then 2 and 70,625,613.5 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 | 141,251,227 | |
| -1 | -141,251,227 |
Now, we try dividing 141,251,227 by 3:
141,251,227 ÷ 3 = 47,083,742.3333
If the quotient is a whole number, then 3 and 47,083,742.3333 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 | 141,251,227 | |
| -1 | -141,251,227 |
Let's try dividing by 4:
141,251,227 ÷ 4 = 35,312,806.75
If the quotient is a whole number, then 4 and 35,312,806.75 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 | 141,251,227 | |
| -1 | 141,251,227 |
If you did it right, you will end up with this table:
| 1 | 13 | 101 | 179 | 601 | 1,313 | 2,327 | 7,813 | 18,079 | 60,701 | 107,579 | 235,027 | 789,113 | 1,398,527 | 10,865,479 | 141,251,227 |
| -1 | -13 | -101 | -179 | -601 | -1,313 | -2,327 | -7,813 | -18,079 | -60,701 | -107,579 | -235,027 | -789,113 | -1,398,527 | -10,865,479 | -141,251,227 |
