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 253,454,737, 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 | 253,454,737 | |
| -1 | -253,454,737 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 253,454,737.
Example:
1 x 253,454,737 = 253,454,737
and
-1 x -253,454,737 = 253,454,737
Notice both answers equal 253,454,737
With that explanation out of the way, let's continue. Next, we take the number 253,454,737 and divide it by 2:
253,454,737 ÷ 2 = 126,727,368.5
If the quotient is a whole number, then 2 and 126,727,368.5 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 | 253,454,737 | |
| -1 | -253,454,737 |
Now, we try dividing 253,454,737 by 3:
253,454,737 ÷ 3 = 84,484,912.3333
If the quotient is a whole number, then 3 and 84,484,912.3333 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 | 253,454,737 | |
| -1 | -253,454,737 |
Let's try dividing by 4:
253,454,737 ÷ 4 = 63,363,684.25
If the quotient is a whole number, then 4 and 63,363,684.25 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 | 253,454,737 | |
| -1 | 253,454,737 |
If you did it right, you will end up with this table:
| 1 | 19 | 59 | 311 | 727 | 1,121 | 5,909 | 13,813 | 18,349 | 42,893 | 226,097 | 348,631 | 814,967 | 4,295,843 | 13,339,723 | 253,454,737 |
| -1 | -19 | -59 | -311 | -727 | -1,121 | -5,909 | -13,813 | -18,349 | -42,893 | -226,097 | -348,631 | -814,967 | -4,295,843 | -13,339,723 | -253,454,737 |
