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 56,454,155, 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 | 56,454,155 | |
| -1 | -56,454,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,454,155.
Example:
1 x 56,454,155 = 56,454,155
and
-1 x -56,454,155 = 56,454,155
Notice both answers equal 56,454,155
With that explanation out of the way, let's continue. Next, we take the number 56,454,155 and divide it by 2:
56,454,155 ÷ 2 = 28,227,077.5
If the quotient is a whole number, then 2 and 28,227,077.5 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 | 56,454,155 | |
| -1 | -56,454,155 |
Now, we try dividing 56,454,155 by 3:
56,454,155 ÷ 3 = 18,818,051.6667
If the quotient is a whole number, then 3 and 18,818,051.6667 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 | 56,454,155 | |
| -1 | -56,454,155 |
Let's try dividing by 4:
56,454,155 ÷ 4 = 14,113,538.75
If the quotient is a whole number, then 4 and 14,113,538.75 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 | 56,454,155 | |
| -1 | 56,454,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 139 | 145 | 695 | 2,801 | 4,031 | 14,005 | 20,155 | 81,229 | 389,339 | 406,145 | 1,946,695 | 11,290,831 | 56,454,155 |
| -1 | -5 | -29 | -139 | -145 | -695 | -2,801 | -4,031 | -14,005 | -20,155 | -81,229 | -389,339 | -406,145 | -1,946,695 | -11,290,831 | -56,454,155 |
