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 56,345,575, 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 | 56,345,575 | |
| -1 | -56,345,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,345,575.
Example:
1 x 56,345,575 = 56,345,575
and
-1 x -56,345,575 = 56,345,575
Notice both answers equal 56,345,575
With that explanation out of the way, let's continue. Next, we take the number 56,345,575 and divide it by 2:
56,345,575 ÷ 2 = 28,172,787.5
If the quotient is a whole number, then 2 and 28,172,787.5 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 | 56,345,575 | |
| -1 | -56,345,575 |
Now, we try dividing 56,345,575 by 3:
56,345,575 ÷ 3 = 18,781,858.3333
If the quotient is a whole number, then 3 and 18,781,858.3333 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 | 56,345,575 | |
| -1 | -56,345,575 |
Let's try dividing by 4:
56,345,575 ÷ 4 = 14,086,393.75
If the quotient is a whole number, then 4 and 14,086,393.75 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 | 56,345,575 | |
| -1 | 56,345,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 143 | 275 | 325 | 715 | 3,575 | 15,761 | 78,805 | 173,371 | 204,893 | 394,025 | 866,855 | 1,024,465 | 2,253,823 | 4,334,275 | 5,122,325 | 11,269,115 | 56,345,575 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -143 | -275 | -325 | -715 | -3,575 | -15,761 | -78,805 | -173,371 | -204,893 | -394,025 | -866,855 | -1,024,465 | -2,253,823 | -4,334,275 | -5,122,325 | -11,269,115 | -56,345,575 |
