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 57,812,209, 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 | 57,812,209 | |
| -1 | -57,812,209 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,812,209.
Example:
1 x 57,812,209 = 57,812,209
and
-1 x -57,812,209 = 57,812,209
Notice both answers equal 57,812,209
With that explanation out of the way, let's continue. Next, we take the number 57,812,209 and divide it by 2:
57,812,209 ÷ 2 = 28,906,104.5
If the quotient is a whole number, then 2 and 28,906,104.5 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 | 57,812,209 | |
| -1 | -57,812,209 |
Now, we try dividing 57,812,209 by 3:
57,812,209 ÷ 3 = 19,270,736.3333
If the quotient is a whole number, then 3 and 19,270,736.3333 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 | 57,812,209 | |
| -1 | -57,812,209 |
Let's try dividing by 4:
57,812,209 ÷ 4 = 14,453,052.25
If the quotient is a whole number, then 4 and 14,453,052.25 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 | 57,812,209 | |
| -1 | 57,812,209 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 47 | 49 | 91 | 329 | 611 | 637 | 1,931 | 2,303 | 4,277 | 13,517 | 25,103 | 29,939 | 90,757 | 94,619 | 175,721 | 635,299 | 1,179,841 | 1,230,047 | 4,447,093 | 8,258,887 | 57,812,209 |
| -1 | -7 | -13 | -47 | -49 | -91 | -329 | -611 | -637 | -1,931 | -2,303 | -4,277 | -13,517 | -25,103 | -29,939 | -90,757 | -94,619 | -175,721 | -635,299 | -1,179,841 | -1,230,047 | -4,447,093 | -8,258,887 | -57,812,209 |
