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 353,421,523, 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 | 353,421,523 | |
| -1 | -353,421,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 353,421,523.
Example:
1 x 353,421,523 = 353,421,523
and
-1 x -353,421,523 = 353,421,523
Notice both answers equal 353,421,523
With that explanation out of the way, let's continue. Next, we take the number 353,421,523 and divide it by 2:
353,421,523 ÷ 2 = 176,710,761.5
If the quotient is a whole number, then 2 and 176,710,761.5 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 | 353,421,523 | |
| -1 | -353,421,523 |
Now, we try dividing 353,421,523 by 3:
353,421,523 ÷ 3 = 117,807,174.3333
If the quotient is a whole number, then 3 and 117,807,174.3333 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 | 353,421,523 | |
| -1 | -353,421,523 |
Let's try dividing by 4:
353,421,523 ÷ 4 = 88,355,380.75
If the quotient is a whole number, then 4 and 88,355,380.75 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 | 353,421,523 | |
| -1 | 353,421,523 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 101 | 707 | 1,313 | 9,191 | 38,453 | 269,171 | 499,889 | 3,499,223 | 3,883,753 | 27,186,271 | 50,488,789 | 353,421,523 |
| -1 | -7 | -13 | -91 | -101 | -707 | -1,313 | -9,191 | -38,453 | -269,171 | -499,889 | -3,499,223 | -3,883,753 | -27,186,271 | -50,488,789 | -353,421,523 |
