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 54,556,411, 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 | 54,556,411 | |
| -1 | -54,556,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,556,411.
Example:
1 x 54,556,411 = 54,556,411
and
-1 x -54,556,411 = 54,556,411
Notice both answers equal 54,556,411
With that explanation out of the way, let's continue. Next, we take the number 54,556,411 and divide it by 2:
54,556,411 ÷ 2 = 27,278,205.5
If the quotient is a whole number, then 2 and 27,278,205.5 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 | 54,556,411 | |
| -1 | -54,556,411 |
Now, we try dividing 54,556,411 by 3:
54,556,411 ÷ 3 = 18,185,470.3333
If the quotient is a whole number, then 3 and 18,185,470.3333 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 | 54,556,411 | |
| -1 | -54,556,411 |
Let's try dividing by 4:
54,556,411 ÷ 4 = 13,639,102.75
If the quotient is a whole number, then 4 and 13,639,102.75 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 | 54,556,411 | |
| -1 | 54,556,411 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 107 | 169 | 431 | 749 | 1,183 | 1,391 | 3,017 | 5,603 | 9,737 | 18,083 | 39,221 | 46,117 | 72,839 | 126,581 | 322,819 | 509,873 | 599,521 | 4,196,647 | 7,793,773 | 54,556,411 |
| -1 | -7 | -13 | -91 | -107 | -169 | -431 | -749 | -1,183 | -1,391 | -3,017 | -5,603 | -9,737 | -18,083 | -39,221 | -46,117 | -72,839 | -126,581 | -322,819 | -509,873 | -599,521 | -4,196,647 | -7,793,773 | -54,556,411 |
