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 57,726,851, 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 | 57,726,851 | |
| -1 | -57,726,851 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,726,851.
Example:
1 x 57,726,851 = 57,726,851
and
-1 x -57,726,851 = 57,726,851
Notice both answers equal 57,726,851
With that explanation out of the way, let's continue. Next, we take the number 57,726,851 and divide it by 2:
57,726,851 ÷ 2 = 28,863,425.5
If the quotient is a whole number, then 2 and 28,863,425.5 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 | 57,726,851 | |
| -1 | -57,726,851 |
Now, we try dividing 57,726,851 by 3:
57,726,851 ÷ 3 = 19,242,283.6667
If the quotient is a whole number, then 3 and 19,242,283.6667 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 | 57,726,851 | |
| -1 | -57,726,851 |
Let's try dividing by 4:
57,726,851 ÷ 4 = 14,431,712.75
If the quotient is a whole number, then 4 and 14,431,712.75 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 | 57,726,851 | |
| -1 | 57,726,851 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 169 | 637 | 1,183 | 6,971 | 8,281 | 48,797 | 90,623 | 341,579 | 634,361 | 1,178,099 | 4,440,527 | 8,246,693 | 57,726,851 |
| -1 | -7 | -13 | -49 | -91 | -169 | -637 | -1,183 | -6,971 | -8,281 | -48,797 | -90,623 | -341,579 | -634,361 | -1,178,099 | -4,440,527 | -8,246,693 | -57,726,851 |
