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 353,778,847, 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 | 353,778,847 | |
| -1 | -353,778,847 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 353,778,847.
Example:
1 x 353,778,847 = 353,778,847
and
-1 x -353,778,847 = 353,778,847
Notice both answers equal 353,778,847
With that explanation out of the way, let's continue. Next, we take the number 353,778,847 and divide it by 2:
353,778,847 ÷ 2 = 176,889,423.5
If the quotient is a whole number, then 2 and 176,889,423.5 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 | 353,778,847 | |
| -1 | -353,778,847 |
Now, we try dividing 353,778,847 by 3:
353,778,847 ÷ 3 = 117,926,282.3333
If the quotient is a whole number, then 3 and 117,926,282.3333 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 | 353,778,847 | |
| -1 | -353,778,847 |
Let's try dividing by 4:
353,778,847 ÷ 4 = 88,444,711.75
If the quotient is a whole number, then 4 and 88,444,711.75 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 | 353,778,847 | |
| -1 | 353,778,847 |
If you did it right, you will end up with this table:
| 1 | 23 | 211 | 269 | 271 | 4,853 | 6,187 | 6,233 | 56,759 | 57,181 | 72,899 | 1,305,457 | 1,315,163 | 1,676,677 | 15,381,689 | 353,778,847 |
| -1 | -23 | -211 | -269 | -271 | -4,853 | -6,187 | -6,233 | -56,759 | -57,181 | -72,899 | -1,305,457 | -1,315,163 | -1,676,677 | -15,381,689 | -353,778,847 |
