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 110,512,451, 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 | 110,512,451 | |
| -1 | -110,512,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,512,451.
Example:
1 x 110,512,451 = 110,512,451
and
-1 x -110,512,451 = 110,512,451
Notice both answers equal 110,512,451
With that explanation out of the way, let's continue. Next, we take the number 110,512,451 and divide it by 2:
110,512,451 ÷ 2 = 55,256,225.5
If the quotient is a whole number, then 2 and 55,256,225.5 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 | 110,512,451 | |
| -1 | -110,512,451 |
Now, we try dividing 110,512,451 by 3:
110,512,451 ÷ 3 = 36,837,483.6667
If the quotient is a whole number, then 3 and 36,837,483.6667 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 | 110,512,451 | |
| -1 | -110,512,451 |
Let's try dividing by 4:
110,512,451 ÷ 4 = 27,628,112.75
If the quotient is a whole number, then 4 and 27,628,112.75 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 | 110,512,451 | |
| -1 | 110,512,451 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 43 | 259 | 301 | 1,591 | 9,923 | 11,137 | 69,461 | 367,151 | 426,689 | 2,570,057 | 2,986,823 | 15,787,493 | 110,512,451 |
| -1 | -7 | -37 | -43 | -259 | -301 | -1,591 | -9,923 | -11,137 | -69,461 | -367,151 | -426,689 | -2,570,057 | -2,986,823 | -15,787,493 | -110,512,451 |
