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 53,552,389, 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 | 53,552,389 | |
| -1 | -53,552,389 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,552,389.
Example:
1 x 53,552,389 = 53,552,389
and
-1 x -53,552,389 = 53,552,389
Notice both answers equal 53,552,389
With that explanation out of the way, let's continue. Next, we take the number 53,552,389 and divide it by 2:
53,552,389 ÷ 2 = 26,776,194.5
If the quotient is a whole number, then 2 and 26,776,194.5 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 | 53,552,389 | |
| -1 | -53,552,389 |
Now, we try dividing 53,552,389 by 3:
53,552,389 ÷ 3 = 17,850,796.3333
If the quotient is a whole number, then 3 and 17,850,796.3333 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 | 53,552,389 | |
| -1 | -53,552,389 |
Let's try dividing by 4:
53,552,389 ÷ 4 = 13,388,097.25
If the quotient is a whole number, then 4 and 13,388,097.25 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 | 53,552,389 | |
| -1 | 53,552,389 |
If you did it right, you will end up with this table:
| 1 | 11 | 71 | 191 | 359 | 781 | 2,101 | 3,949 | 13,561 | 25,489 | 68,569 | 149,171 | 280,379 | 754,259 | 4,868,399 | 53,552,389 |
| -1 | -11 | -71 | -191 | -359 | -781 | -2,101 | -3,949 | -13,561 | -25,489 | -68,569 | -149,171 | -280,379 | -754,259 | -4,868,399 | -53,552,389 |
