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 411,432,251, 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 | 411,432,251 | |
| -1 | -411,432,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 411,432,251.
Example:
1 x 411,432,251 = 411,432,251
and
-1 x -411,432,251 = 411,432,251
Notice both answers equal 411,432,251
With that explanation out of the way, let's continue. Next, we take the number 411,432,251 and divide it by 2:
411,432,251 ÷ 2 = 205,716,125.5
If the quotient is a whole number, then 2 and 205,716,125.5 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 | 411,432,251 | |
| -1 | -411,432,251 |
Now, we try dividing 411,432,251 by 3:
411,432,251 ÷ 3 = 137,144,083.6667
If the quotient is a whole number, then 3 and 137,144,083.6667 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 | 411,432,251 | |
| -1 | -411,432,251 |
Let's try dividing by 4:
411,432,251 ÷ 4 = 102,858,062.75
If the quotient is a whole number, then 4 and 102,858,062.75 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 | 411,432,251 | |
| -1 | 411,432,251 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 61 | 551 | 1,159 | 1,769 | 12,241 | 33,611 | 232,579 | 354,989 | 746,701 | 6,744,791 | 14,187,319 | 21,654,329 | 411,432,251 |
| -1 | -19 | -29 | -61 | -551 | -1,159 | -1,769 | -12,241 | -33,611 | -232,579 | -354,989 | -746,701 | -6,744,791 | -14,187,319 | -21,654,329 | -411,432,251 |
