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 56,581,567, 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 | 56,581,567 | |
| -1 | -56,581,567 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,581,567.
Example:
1 x 56,581,567 = 56,581,567
and
-1 x -56,581,567 = 56,581,567
Notice both answers equal 56,581,567
With that explanation out of the way, let's continue. Next, we take the number 56,581,567 and divide it by 2:
56,581,567 ÷ 2 = 28,290,783.5
If the quotient is a whole number, then 2 and 28,290,783.5 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 | 56,581,567 | |
| -1 | -56,581,567 |
Now, we try dividing 56,581,567 by 3:
56,581,567 ÷ 3 = 18,860,522.3333
If the quotient is a whole number, then 3 and 18,860,522.3333 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 | 56,581,567 | |
| -1 | -56,581,567 |
Let's try dividing by 4:
56,581,567 ÷ 4 = 14,145,391.75
If the quotient is a whole number, then 4 and 14,145,391.75 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 | 56,581,567 | |
| -1 | 56,581,567 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 223 | 469 | 541 | 1,561 | 3,787 | 14,941 | 36,247 | 104,587 | 120,643 | 253,729 | 844,501 | 8,083,081 | 56,581,567 |
| -1 | -7 | -67 | -223 | -469 | -541 | -1,561 | -3,787 | -14,941 | -36,247 | -104,587 | -120,643 | -253,729 | -844,501 | -8,083,081 | -56,581,567 |
