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 5,440,213, 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 | 5,440,213 | |
| -1 | -5,440,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,440,213.
Example:
1 x 5,440,213 = 5,440,213
and
-1 x -5,440,213 = 5,440,213
Notice both answers equal 5,440,213
With that explanation out of the way, let's continue. Next, we take the number 5,440,213 and divide it by 2:
5,440,213 ÷ 2 = 2,720,106.5
If the quotient is a whole number, then 2 and 2,720,106.5 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 | 5,440,213 | |
| -1 | -5,440,213 |
Now, we try dividing 5,440,213 by 3:
5,440,213 ÷ 3 = 1,813,404.3333
If the quotient is a whole number, then 3 and 1,813,404.3333 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 | 5,440,213 | |
| -1 | -5,440,213 |
Let's try dividing by 4:
5,440,213 ÷ 4 = 1,360,053.25
If the quotient is a whole number, then 4 and 1,360,053.25 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 | 5,440,213 | |
| -1 | 5,440,213 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 59 | 211 | 437 | 1,121 | 1,357 | 4,009 | 4,853 | 12,449 | 25,783 | 92,207 | 236,531 | 286,327 | 5,440,213 |
| -1 | -19 | -23 | -59 | -211 | -437 | -1,121 | -1,357 | -4,009 | -4,853 | -12,449 | -25,783 | -92,207 | -236,531 | -286,327 | -5,440,213 |
