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 353,183,825, 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 | 353,183,825 | |
| -1 | -353,183,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 353,183,825.
Example:
1 x 353,183,825 = 353,183,825
and
-1 x -353,183,825 = 353,183,825
Notice both answers equal 353,183,825
With that explanation out of the way, let's continue. Next, we take the number 353,183,825 and divide it by 2:
353,183,825 ÷ 2 = 176,591,912.5
If the quotient is a whole number, then 2 and 176,591,912.5 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 | 353,183,825 | |
| -1 | -353,183,825 |
Now, we try dividing 353,183,825 by 3:
353,183,825 ÷ 3 = 117,727,941.6667
If the quotient is a whole number, then 3 and 117,727,941.6667 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 | 353,183,825 | |
| -1 | -353,183,825 |
Let's try dividing by 4:
353,183,825 ÷ 4 = 88,295,956.25
If the quotient is a whole number, then 4 and 88,295,956.25 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 | 353,183,825 | |
| -1 | 353,183,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 127 | 173 | 635 | 643 | 865 | 3,175 | 3,215 | 4,325 | 16,075 | 21,971 | 81,661 | 109,855 | 111,239 | 408,305 | 549,275 | 556,195 | 2,041,525 | 2,780,975 | 14,127,353 | 70,636,765 | 353,183,825 |
| -1 | -5 | -25 | -127 | -173 | -635 | -643 | -865 | -3,175 | -3,215 | -4,325 | -16,075 | -21,971 | -81,661 | -109,855 | -111,239 | -408,305 | -549,275 | -556,195 | -2,041,525 | -2,780,975 | -14,127,353 | -70,636,765 | -353,183,825 |
