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 54,065,141, 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 | 54,065,141 | |
| -1 | -54,065,141 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,065,141.
Example:
1 x 54,065,141 = 54,065,141
and
-1 x -54,065,141 = 54,065,141
Notice both answers equal 54,065,141
With that explanation out of the way, let's continue. Next, we take the number 54,065,141 and divide it by 2:
54,065,141 ÷ 2 = 27,032,570.5
If the quotient is a whole number, then 2 and 27,032,570.5 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 | 54,065,141 | |
| -1 | -54,065,141 |
Now, we try dividing 54,065,141 by 3:
54,065,141 ÷ 3 = 18,021,713.6667
If the quotient is a whole number, then 3 and 18,021,713.6667 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 | 54,065,141 | |
| -1 | -54,065,141 |
Let's try dividing by 4:
54,065,141 ÷ 4 = 13,516,285.25
If the quotient is a whole number, then 4 and 13,516,285.25 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 | 54,065,141 | |
| -1 | 54,065,141 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 131 | 599 | 689 | 1,703 | 6,943 | 7,787 | 31,747 | 78,469 | 90,259 | 412,711 | 1,020,097 | 4,158,857 | 54,065,141 |
| -1 | -13 | -53 | -131 | -599 | -689 | -1,703 | -6,943 | -7,787 | -31,747 | -78,469 | -90,259 | -412,711 | -1,020,097 | -4,158,857 | -54,065,141 |
