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 113,122,555, 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 | 113,122,555 | |
| -1 | -113,122,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,122,555.
Example:
1 x 113,122,555 = 113,122,555
and
-1 x -113,122,555 = 113,122,555
Notice both answers equal 113,122,555
With that explanation out of the way, let's continue. Next, we take the number 113,122,555 and divide it by 2:
113,122,555 ÷ 2 = 56,561,277.5
If the quotient is a whole number, then 2 and 56,561,277.5 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 | 113,122,555 | |
| -1 | -113,122,555 |
Now, we try dividing 113,122,555 by 3:
113,122,555 ÷ 3 = 37,707,518.3333
If the quotient is a whole number, then 3 and 37,707,518.3333 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 | 113,122,555 | |
| -1 | -113,122,555 |
Let's try dividing by 4:
113,122,555 ÷ 4 = 28,280,638.75
If the quotient is a whole number, then 4 and 28,280,638.75 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 | 113,122,555 | |
| -1 | 113,122,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 248,621 | 1,243,105 | 1,740,347 | 3,232,073 | 8,701,735 | 16,160,365 | 22,624,511 | 113,122,555 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -248,621 | -1,243,105 | -1,740,347 | -3,232,073 | -8,701,735 | -16,160,365 | -22,624,511 | -113,122,555 |
