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 56,676,521, 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 | 56,676,521 | |
| -1 | -56,676,521 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,676,521.
Example:
1 x 56,676,521 = 56,676,521
and
-1 x -56,676,521 = 56,676,521
Notice both answers equal 56,676,521
With that explanation out of the way, let's continue. Next, we take the number 56,676,521 and divide it by 2:
56,676,521 ÷ 2 = 28,338,260.5
If the quotient is a whole number, then 2 and 28,338,260.5 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 | 56,676,521 | |
| -1 | -56,676,521 |
Now, we try dividing 56,676,521 by 3:
56,676,521 ÷ 3 = 18,892,173.6667
If the quotient is a whole number, then 3 and 18,892,173.6667 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 | 56,676,521 | |
| -1 | -56,676,521 |
Let's try dividing by 4:
56,676,521 ÷ 4 = 14,169,130.25
If the quotient is a whole number, then 4 and 14,169,130.25 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 | 56,676,521 | |
| -1 | 56,676,521 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 59 | 121 | 187 | 467 | 649 | 1,003 | 2,057 | 5,137 | 7,139 | 7,939 | 11,033 | 27,553 | 56,507 | 87,329 | 121,363 | 303,083 | 468,401 | 960,619 | 3,333,913 | 5,152,411 | 56,676,521 |
| -1 | -11 | -17 | -59 | -121 | -187 | -467 | -649 | -1,003 | -2,057 | -5,137 | -7,139 | -7,939 | -11,033 | -27,553 | -56,507 | -87,329 | -121,363 | -303,083 | -468,401 | -960,619 | -3,333,913 | -5,152,411 | -56,676,521 |
