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 347,556,155, 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 | 347,556,155 | |
| -1 | -347,556,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 347,556,155.
Example:
1 x 347,556,155 = 347,556,155
and
-1 x -347,556,155 = 347,556,155
Notice both answers equal 347,556,155
With that explanation out of the way, let's continue. Next, we take the number 347,556,155 and divide it by 2:
347,556,155 ÷ 2 = 173,778,077.5
If the quotient is a whole number, then 2 and 173,778,077.5 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 | 347,556,155 | |
| -1 | -347,556,155 |
Now, we try dividing 347,556,155 by 3:
347,556,155 ÷ 3 = 115,852,051.6667
If the quotient is a whole number, then 3 and 115,852,051.6667 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 | 347,556,155 | |
| -1 | -347,556,155 |
Let's try dividing by 4:
347,556,155 ÷ 4 = 86,889,038.75
If the quotient is a whole number, then 4 and 86,889,038.75 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 | 347,556,155 | |
| -1 | 347,556,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 79 | 145 | 395 | 2,291 | 11,455 | 30,341 | 151,705 | 879,889 | 2,396,939 | 4,399,445 | 11,984,695 | 69,511,231 | 347,556,155 |
| -1 | -5 | -29 | -79 | -145 | -395 | -2,291 | -11,455 | -30,341 | -151,705 | -879,889 | -2,396,939 | -4,399,445 | -11,984,695 | -69,511,231 | -347,556,155 |
