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 57,151,705, 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 | 57,151,705 | |
| -1 | -57,151,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,151,705.
Example:
1 x 57,151,705 = 57,151,705
and
-1 x -57,151,705 = 57,151,705
Notice both answers equal 57,151,705
With that explanation out of the way, let's continue. Next, we take the number 57,151,705 and divide it by 2:
57,151,705 ÷ 2 = 28,575,852.5
If the quotient is a whole number, then 2 and 28,575,852.5 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 | 57,151,705 | |
| -1 | -57,151,705 |
Now, we try dividing 57,151,705 by 3:
57,151,705 ÷ 3 = 19,050,568.3333
If the quotient is a whole number, then 3 and 19,050,568.3333 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 | 57,151,705 | |
| -1 | -57,151,705 |
Let's try dividing by 4:
57,151,705 ÷ 4 = 14,287,926.25
If the quotient is a whole number, then 4 and 14,287,926.25 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 | 57,151,705 | |
| -1 | 57,151,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 51,721 | 258,605 | 672,373 | 879,257 | 3,361,865 | 4,396,285 | 11,430,341 | 57,151,705 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -51,721 | -258,605 | -672,373 | -879,257 | -3,361,865 | -4,396,285 | -11,430,341 | -57,151,705 |
