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 53,979,121, 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 | 53,979,121 | |
| -1 | -53,979,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,979,121.
Example:
1 x 53,979,121 = 53,979,121
and
-1 x -53,979,121 = 53,979,121
Notice both answers equal 53,979,121
With that explanation out of the way, let's continue. Next, we take the number 53,979,121 and divide it by 2:
53,979,121 ÷ 2 = 26,989,560.5
If the quotient is a whole number, then 2 and 26,989,560.5 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 | 53,979,121 | |
| -1 | -53,979,121 |
Now, we try dividing 53,979,121 by 3:
53,979,121 ÷ 3 = 17,993,040.3333
If the quotient is a whole number, then 3 and 17,993,040.3333 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 | 53,979,121 | |
| -1 | -53,979,121 |
Let's try dividing by 4:
53,979,121 ÷ 4 = 13,494,780.25
If the quotient is a whole number, then 4 and 13,494,780.25 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 | 53,979,121 | |
| -1 | 53,979,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 139 | 203 | 973 | 1,913 | 4,031 | 13,391 | 28,217 | 55,477 | 265,907 | 388,339 | 1,861,349 | 7,711,303 | 53,979,121 |
| -1 | -7 | -29 | -139 | -203 | -973 | -1,913 | -4,031 | -13,391 | -28,217 | -55,477 | -265,907 | -388,339 | -1,861,349 | -7,711,303 | -53,979,121 |
