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 541,465,249, 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 | 541,465,249 | |
| -1 | -541,465,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 541,465,249.
Example:
1 x 541,465,249 = 541,465,249
and
-1 x -541,465,249 = 541,465,249
Notice both answers equal 541,465,249
With that explanation out of the way, let's continue. Next, we take the number 541,465,249 and divide it by 2:
541,465,249 ÷ 2 = 270,732,624.5
If the quotient is a whole number, then 2 and 270,732,624.5 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 | 541,465,249 | |
| -1 | -541,465,249 |
Now, we try dividing 541,465,249 by 3:
541,465,249 ÷ 3 = 180,488,416.3333
If the quotient is a whole number, then 3 and 180,488,416.3333 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 | 541,465,249 | |
| -1 | -541,465,249 |
Let's try dividing by 4:
541,465,249 ÷ 4 = 135,366,312.25
If the quotient is a whole number, then 4 and 135,366,312.25 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 | 541,465,249 | |
| -1 | 541,465,249 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 19 | 221 | 247 | 323 | 4,199 | 128,951 | 1,676,363 | 2,192,167 | 2,450,069 | 28,498,171 | 31,850,897 | 41,651,173 | 541,465,249 |
| -1 | -13 | -17 | -19 | -221 | -247 | -323 | -4,199 | -128,951 | -1,676,363 | -2,192,167 | -2,450,069 | -28,498,171 | -31,850,897 | -41,651,173 | -541,465,249 |
