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 356,021,545, 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 | 356,021,545 | |
| -1 | -356,021,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,021,545.
Example:
1 x 356,021,545 = 356,021,545
and
-1 x -356,021,545 = 356,021,545
Notice both answers equal 356,021,545
With that explanation out of the way, let's continue. Next, we take the number 356,021,545 and divide it by 2:
356,021,545 ÷ 2 = 178,010,772.5
If the quotient is a whole number, then 2 and 178,010,772.5 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 | 356,021,545 | |
| -1 | -356,021,545 |
Now, we try dividing 356,021,545 by 3:
356,021,545 ÷ 3 = 118,673,848.3333
If the quotient is a whole number, then 3 and 118,673,848.3333 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 | 356,021,545 | |
| -1 | -356,021,545 |
Let's try dividing by 4:
356,021,545 ÷ 4 = 89,005,386.25
If the quotient is a whole number, then 4 and 89,005,386.25 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 | 356,021,545 | |
| -1 | 356,021,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 223,211 | 1,116,055 | 2,455,321 | 6,473,119 | 12,276,605 | 32,365,595 | 71,204,309 | 356,021,545 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -223,211 | -1,116,055 | -2,455,321 | -6,473,119 | -12,276,605 | -32,365,595 | -71,204,309 | -356,021,545 |
