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 187,266,365, 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 | 187,266,365 | |
| -1 | -187,266,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 187,266,365.
Example:
1 x 187,266,365 = 187,266,365
and
-1 x -187,266,365 = 187,266,365
Notice both answers equal 187,266,365
With that explanation out of the way, let's continue. Next, we take the number 187,266,365 and divide it by 2:
187,266,365 ÷ 2 = 93,633,182.5
If the quotient is a whole number, then 2 and 93,633,182.5 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 | 187,266,365 | |
| -1 | -187,266,365 |
Now, we try dividing 187,266,365 by 3:
187,266,365 ÷ 3 = 62,422,121.6667
If the quotient is a whole number, then 3 and 62,422,121.6667 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 | 187,266,365 | |
| -1 | -187,266,365 |
Let's try dividing by 4:
187,266,365 ÷ 4 = 46,816,591.25
If the quotient is a whole number, then 4 and 46,816,591.25 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 | 187,266,365 | |
| -1 | 187,266,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 169 | 715 | 845 | 1,859 | 9,295 | 20,147 | 100,735 | 221,617 | 261,911 | 1,108,085 | 1,309,555 | 2,881,021 | 3,404,843 | 14,405,105 | 17,024,215 | 37,453,273 | 187,266,365 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -169 | -715 | -845 | -1,859 | -9,295 | -20,147 | -100,735 | -221,617 | -261,911 | -1,108,085 | -1,309,555 | -2,881,021 | -3,404,843 | -14,405,105 | -17,024,215 | -37,453,273 | -187,266,365 |
