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 56,119,207, 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 | 56,119,207 | |
| -1 | -56,119,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,119,207.
Example:
1 x 56,119,207 = 56,119,207
and
-1 x -56,119,207 = 56,119,207
Notice both answers equal 56,119,207
With that explanation out of the way, let's continue. Next, we take the number 56,119,207 and divide it by 2:
56,119,207 ÷ 2 = 28,059,603.5
If the quotient is a whole number, then 2 and 28,059,603.5 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 | 56,119,207 | |
| -1 | -56,119,207 |
Now, we try dividing 56,119,207 by 3:
56,119,207 ÷ 3 = 18,706,402.3333
If the quotient is a whole number, then 3 and 18,706,402.3333 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 | 56,119,207 | |
| -1 | -56,119,207 |
Let's try dividing by 4:
56,119,207 ÷ 4 = 14,029,801.75
If the quotient is a whole number, then 4 and 14,029,801.75 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 | 56,119,207 | |
| -1 | 56,119,207 |
If you did it right, you will end up with this table:
| 1 | 31 | 59 | 61 | 503 | 1,829 | 1,891 | 3,599 | 15,593 | 29,677 | 30,683 | 111,569 | 919,987 | 951,173 | 1,810,297 | 56,119,207 |
| -1 | -31 | -59 | -61 | -503 | -1,829 | -1,891 | -3,599 | -15,593 | -29,677 | -30,683 | -111,569 | -919,987 | -951,173 | -1,810,297 | -56,119,207 |
