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 57,201,739, 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 | 57,201,739 | |
| -1 | -57,201,739 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,201,739.
Example:
1 x 57,201,739 = 57,201,739
and
-1 x -57,201,739 = 57,201,739
Notice both answers equal 57,201,739
With that explanation out of the way, let's continue. Next, we take the number 57,201,739 and divide it by 2:
57,201,739 ÷ 2 = 28,600,869.5
If the quotient is a whole number, then 2 and 28,600,869.5 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 | 57,201,739 | |
| -1 | -57,201,739 |
Now, we try dividing 57,201,739 by 3:
57,201,739 ÷ 3 = 19,067,246.3333
If the quotient is a whole number, then 3 and 19,067,246.3333 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 | 57,201,739 | |
| -1 | -57,201,739 |
Let's try dividing by 4:
57,201,739 ÷ 4 = 14,300,434.75
If the quotient is a whole number, then 4 and 14,300,434.75 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 | 57,201,739 | |
| -1 | 57,201,739 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 59 | 301 | 413 | 2,537 | 3,221 | 17,759 | 22,547 | 138,503 | 190,039 | 969,521 | 1,330,273 | 8,171,677 | 57,201,739 |
| -1 | -7 | -43 | -59 | -301 | -413 | -2,537 | -3,221 | -17,759 | -22,547 | -138,503 | -190,039 | -969,521 | -1,330,273 | -8,171,677 | -57,201,739 |
