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 118,875,799, 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 | 118,875,799 | |
| -1 | -118,875,799 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 118,875,799.
Example:
1 x 118,875,799 = 118,875,799
and
-1 x -118,875,799 = 118,875,799
Notice both answers equal 118,875,799
With that explanation out of the way, let's continue. Next, we take the number 118,875,799 and divide it by 2:
118,875,799 ÷ 2 = 59,437,899.5
If the quotient is a whole number, then 2 and 59,437,899.5 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 | 118,875,799 | |
| -1 | -118,875,799 |
Now, we try dividing 118,875,799 by 3:
118,875,799 ÷ 3 = 39,625,266.3333
If the quotient is a whole number, then 3 and 39,625,266.3333 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 | 118,875,799 | |
| -1 | -118,875,799 |
Let's try dividing by 4:
118,875,799 ÷ 4 = 29,718,949.75
If the quotient is a whole number, then 4 and 29,718,949.75 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 | 118,875,799 | |
| -1 | 118,875,799 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 133 | 161 | 437 | 3,059 | 38,861 | 272,027 | 738,359 | 893,803 | 5,168,513 | 6,256,621 | 16,982,257 | 118,875,799 |
| -1 | -7 | -19 | -23 | -133 | -161 | -437 | -3,059 | -38,861 | -272,027 | -738,359 | -893,803 | -5,168,513 | -6,256,621 | -16,982,257 | -118,875,799 |
