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 54,363,139, 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 | 54,363,139 | |
| -1 | -54,363,139 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,363,139.
Example:
1 x 54,363,139 = 54,363,139
and
-1 x -54,363,139 = 54,363,139
Notice both answers equal 54,363,139
With that explanation out of the way, let's continue. Next, we take the number 54,363,139 and divide it by 2:
54,363,139 ÷ 2 = 27,181,569.5
If the quotient is a whole number, then 2 and 27,181,569.5 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 | 54,363,139 | |
| -1 | -54,363,139 |
Now, we try dividing 54,363,139 by 3:
54,363,139 ÷ 3 = 18,121,046.3333
If the quotient is a whole number, then 3 and 18,121,046.3333 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 | 54,363,139 | |
| -1 | -54,363,139 |
Let's try dividing by 4:
54,363,139 ÷ 4 = 13,590,784.75
If the quotient is a whole number, then 4 and 13,590,784.75 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 | 54,363,139 | |
| -1 | 54,363,139 |
If you did it right, you will end up with this table:
| 1 | 29 | 61 | 79 | 389 | 1,769 | 2,291 | 4,819 | 11,281 | 23,729 | 30,731 | 139,751 | 688,141 | 891,199 | 1,874,591 | 54,363,139 |
| -1 | -29 | -61 | -79 | -389 | -1,769 | -2,291 | -4,819 | -11,281 | -23,729 | -30,731 | -139,751 | -688,141 | -891,199 | -1,874,591 | -54,363,139 |
