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 366,531,145, 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 | 366,531,145 | |
| -1 | -366,531,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 366,531,145.
Example:
1 x 366,531,145 = 366,531,145
and
-1 x -366,531,145 = 366,531,145
Notice both answers equal 366,531,145
With that explanation out of the way, let's continue. Next, we take the number 366,531,145 and divide it by 2:
366,531,145 ÷ 2 = 183,265,572.5
If the quotient is a whole number, then 2 and 183,265,572.5 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 | 366,531,145 | |
| -1 | -366,531,145 |
Now, we try dividing 366,531,145 by 3:
366,531,145 ÷ 3 = 122,177,048.3333
If the quotient is a whole number, then 3 and 122,177,048.3333 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 | 366,531,145 | |
| -1 | -366,531,145 |
Let's try dividing by 4:
366,531,145 ÷ 4 = 91,632,786.25
If the quotient is a whole number, then 4 and 91,632,786.25 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 | 366,531,145 | |
| -1 | 366,531,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 47 | 145 | 235 | 1,363 | 6,815 | 53,783 | 268,915 | 1,559,707 | 2,527,801 | 7,798,535 | 12,639,005 | 73,306,229 | 366,531,145 |
| -1 | -5 | -29 | -47 | -145 | -235 | -1,363 | -6,815 | -53,783 | -268,915 | -1,559,707 | -2,527,801 | -7,798,535 | -12,639,005 | -73,306,229 | -366,531,145 |
