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 362,721,545, 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 | 362,721,545 | |
| -1 | -362,721,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 362,721,545.
Example:
1 x 362,721,545 = 362,721,545
and
-1 x -362,721,545 = 362,721,545
Notice both answers equal 362,721,545
With that explanation out of the way, let's continue. Next, we take the number 362,721,545 and divide it by 2:
362,721,545 ÷ 2 = 181,360,772.5
If the quotient is a whole number, then 2 and 181,360,772.5 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 | 362,721,545 | |
| -1 | -362,721,545 |
Now, we try dividing 362,721,545 by 3:
362,721,545 ÷ 3 = 120,907,181.6667
If the quotient is a whole number, then 3 and 120,907,181.6667 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 | 362,721,545 | |
| -1 | -362,721,545 |
Let's try dividing by 4:
362,721,545 ÷ 4 = 90,680,386.25
If the quotient is a whole number, then 4 and 90,680,386.25 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 | 362,721,545 | |
| -1 | 362,721,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 37 | 155 | 185 | 1,147 | 5,735 | 63,247 | 316,235 | 1,960,657 | 2,340,139 | 9,803,285 | 11,700,695 | 72,544,309 | 362,721,545 |
| -1 | -5 | -31 | -37 | -155 | -185 | -1,147 | -5,735 | -63,247 | -316,235 | -1,960,657 | -2,340,139 | -9,803,285 | -11,700,695 | -72,544,309 | -362,721,545 |
