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 54,440,221, 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 | 54,440,221 | |
| -1 | -54,440,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,440,221.
Example:
1 x 54,440,221 = 54,440,221
and
-1 x -54,440,221 = 54,440,221
Notice both answers equal 54,440,221
With that explanation out of the way, let's continue. Next, we take the number 54,440,221 and divide it by 2:
54,440,221 ÷ 2 = 27,220,110.5
If the quotient is a whole number, then 2 and 27,220,110.5 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 | 54,440,221 | |
| -1 | -54,440,221 |
Now, we try dividing 54,440,221 by 3:
54,440,221 ÷ 3 = 18,146,740.3333
If the quotient is a whole number, then 3 and 18,146,740.3333 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 | 54,440,221 | |
| -1 | -54,440,221 |
Let's try dividing by 4:
54,440,221 ÷ 4 = 13,610,055.25
If the quotient is a whole number, then 4 and 13,610,055.25 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 | 54,440,221 | |
| -1 | 54,440,221 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 157 | 319 | 1,087 | 1,727 | 4,553 | 11,957 | 31,523 | 50,083 | 170,659 | 346,753 | 1,877,249 | 4,949,111 | 54,440,221 |
| -1 | -11 | -29 | -157 | -319 | -1,087 | -1,727 | -4,553 | -11,957 | -31,523 | -50,083 | -170,659 | -346,753 | -1,877,249 | -4,949,111 | -54,440,221 |
