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 187,411,055, 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 | 187,411,055 | |
| -1 | -187,411,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 187,411,055.
Example:
1 x 187,411,055 = 187,411,055
and
-1 x -187,411,055 = 187,411,055
Notice both answers equal 187,411,055
With that explanation out of the way, let's continue. Next, we take the number 187,411,055 and divide it by 2:
187,411,055 ÷ 2 = 93,705,527.5
If the quotient is a whole number, then 2 and 93,705,527.5 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 | 187,411,055 | |
| -1 | -187,411,055 |
Now, we try dividing 187,411,055 by 3:
187,411,055 ÷ 3 = 62,470,351.6667
If the quotient is a whole number, then 3 and 62,470,351.6667 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 | 187,411,055 | |
| -1 | -187,411,055 |
Let's try dividing by 4:
187,411,055 ÷ 4 = 46,852,763.75
If the quotient is a whole number, then 4 and 46,852,763.75 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 | 187,411,055 | |
| -1 | 187,411,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 101 | 505 | 1,313 | 6,565 | 28,547 | 142,735 | 371,111 | 1,855,555 | 2,883,247 | 14,416,235 | 37,482,211 | 187,411,055 |
| -1 | -5 | -13 | -65 | -101 | -505 | -1,313 | -6,565 | -28,547 | -142,735 | -371,111 | -1,855,555 | -2,883,247 | -14,416,235 | -37,482,211 | -187,411,055 |
