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 361,562,545, 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 | 361,562,545 | |
| -1 | -361,562,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 361,562,545.
Example:
1 x 361,562,545 = 361,562,545
and
-1 x -361,562,545 = 361,562,545
Notice both answers equal 361,562,545
With that explanation out of the way, let's continue. Next, we take the number 361,562,545 and divide it by 2:
361,562,545 ÷ 2 = 180,781,272.5
If the quotient is a whole number, then 2 and 180,781,272.5 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 | 361,562,545 | |
| -1 | -361,562,545 |
Now, we try dividing 361,562,545 by 3:
361,562,545 ÷ 3 = 120,520,848.3333
If the quotient is a whole number, then 3 and 120,520,848.3333 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 | 361,562,545 | |
| -1 | -361,562,545 |
Let's try dividing by 4:
361,562,545 ÷ 4 = 90,390,636.25
If the quotient is a whole number, then 4 and 90,390,636.25 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 | 361,562,545 | |
| -1 | 361,562,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 727 | 3,635 | 5,851 | 12,359 | 29,255 | 61,795 | 99,467 | 497,335 | 4,253,677 | 21,268,385 | 72,312,509 | 361,562,545 |
| -1 | -5 | -17 | -85 | -727 | -3,635 | -5,851 | -12,359 | -29,255 | -61,795 | -99,467 | -497,335 | -4,253,677 | -21,268,385 | -72,312,509 | -361,562,545 |
