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 113,543,545, 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 | 113,543,545 | |
| -1 | -113,543,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,543,545.
Example:
1 x 113,543,545 = 113,543,545
and
-1 x -113,543,545 = 113,543,545
Notice both answers equal 113,543,545
With that explanation out of the way, let's continue. Next, we take the number 113,543,545 and divide it by 2:
113,543,545 ÷ 2 = 56,771,772.5
If the quotient is a whole number, then 2 and 56,771,772.5 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 | 113,543,545 | |
| -1 | -113,543,545 |
Now, we try dividing 113,543,545 by 3:
113,543,545 ÷ 3 = 37,847,848.3333
If the quotient is a whole number, then 3 and 37,847,848.3333 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 | 113,543,545 | |
| -1 | -113,543,545 |
Let's try dividing by 4:
113,543,545 ÷ 4 = 28,385,886.25
If the quotient is a whole number, then 4 and 28,385,886.25 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 | 113,543,545 | |
| -1 | 113,543,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 137 | 155 | 685 | 4,247 | 5,347 | 21,235 | 26,735 | 165,757 | 732,539 | 828,785 | 3,662,695 | 22,708,709 | 113,543,545 |
| -1 | -5 | -31 | -137 | -155 | -685 | -4,247 | -5,347 | -21,235 | -26,735 | -165,757 | -732,539 | -828,785 | -3,662,695 | -22,708,709 | -113,543,545 |
