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 57,430,205, 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 | 57,430,205 | |
| -1 | -57,430,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,430,205.
Example:
1 x 57,430,205 = 57,430,205
and
-1 x -57,430,205 = 57,430,205
Notice both answers equal 57,430,205
With that explanation out of the way, let's continue. Next, we take the number 57,430,205 and divide it by 2:
57,430,205 ÷ 2 = 28,715,102.5
If the quotient is a whole number, then 2 and 28,715,102.5 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 | 57,430,205 | |
| -1 | -57,430,205 |
Now, we try dividing 57,430,205 by 3:
57,430,205 ÷ 3 = 19,143,401.6667
If the quotient is a whole number, then 3 and 19,143,401.6667 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 | 57,430,205 | |
| -1 | -57,430,205 |
Let's try dividing by 4:
57,430,205 ÷ 4 = 14,357,551.25
If the quotient is a whole number, then 4 and 14,357,551.25 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 | 57,430,205 | |
| -1 | 57,430,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 33,487 | 167,435 | 234,409 | 1,172,045 | 1,640,863 | 8,204,315 | 11,486,041 | 57,430,205 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -33,487 | -167,435 | -234,409 | -1,172,045 | -1,640,863 | -8,204,315 | -11,486,041 | -57,430,205 |
