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 113,020,554, 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 | 113,020,554 | |
| -1 | -113,020,554 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,020,554.
Example:
1 x 113,020,554 = 113,020,554
and
-1 x -113,020,554 = 113,020,554
Notice both answers equal 113,020,554
With that explanation out of the way, let's continue. Next, we take the number 113,020,554 and divide it by 2:
113,020,554 ÷ 2 = 56,510,277
If the quotient is a whole number, then 2 and 56,510,277 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 56,510,277 | 113,020,554 | |
| -1 | -2 | -56,510,277 | -113,020,554 |
Now, we try dividing 113,020,554 by 3:
113,020,554 ÷ 3 = 37,673,518
If the quotient is a whole number, then 3 and 37,673,518 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 37,673,518 | 56,510,277 | 113,020,554 | |
| -1 | -2 | -3 | -37,673,518 | -56,510,277 | -113,020,554 |
Let's try dividing by 4:
113,020,554 ÷ 4 = 28,255,138.5
If the quotient is a whole number, then 4 and 28,255,138.5 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 | 2 | 3 | 37,673,518 | 56,510,277 | 113,020,554 | |
| -1 | -2 | -3 | -37,673,518 | -56,510,277 | 113,020,554 |
If you did it right, you will end up with this table:
| 1 | 2 | 3 | 6 | 173 | 346 | 519 | 1,038 | 108,883 | 217,766 | 326,649 | 653,298 | 18,836,759 | 37,673,518 | 56,510,277 | 113,020,554 |
| -1 | -2 | -3 | -6 | -173 | -346 | -519 | -1,038 | -108,883 | -217,766 | -326,649 | -653,298 | -18,836,759 | -37,673,518 | -56,510,277 | -113,020,554 |
