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 353,224,547, 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 | 353,224,547 | |
| -1 | -353,224,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 353,224,547.
Example:
1 x 353,224,547 = 353,224,547
and
-1 x -353,224,547 = 353,224,547
Notice both answers equal 353,224,547
With that explanation out of the way, let's continue. Next, we take the number 353,224,547 and divide it by 2:
353,224,547 ÷ 2 = 176,612,273.5
If the quotient is a whole number, then 2 and 176,612,273.5 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 | 353,224,547 | |
| -1 | -353,224,547 |
Now, we try dividing 353,224,547 by 3:
353,224,547 ÷ 3 = 117,741,515.6667
If the quotient is a whole number, then 3 and 117,741,515.6667 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 | 353,224,547 | |
| -1 | -353,224,547 |
Let's try dividing by 4:
353,224,547 ÷ 4 = 88,306,136.75
If the quotient is a whole number, then 4 and 88,306,136.75 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 | 353,224,547 | |
| -1 | 353,224,547 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 193 | 299 | 2,509 | 4,439 | 6,121 | 57,707 | 79,573 | 140,783 | 1,181,353 | 1,830,179 | 15,357,589 | 27,171,119 | 353,224,547 |
| -1 | -13 | -23 | -193 | -299 | -2,509 | -4,439 | -6,121 | -57,707 | -79,573 | -140,783 | -1,181,353 | -1,830,179 | -15,357,589 | -27,171,119 | -353,224,547 |
