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 347,132,845, 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 | 347,132,845 | |
| -1 | -347,132,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 347,132,845.
Example:
1 x 347,132,845 = 347,132,845
and
-1 x -347,132,845 = 347,132,845
Notice both answers equal 347,132,845
With that explanation out of the way, let's continue. Next, we take the number 347,132,845 and divide it by 2:
347,132,845 ÷ 2 = 173,566,422.5
If the quotient is a whole number, then 2 and 173,566,422.5 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 | 347,132,845 | |
| -1 | -347,132,845 |
Now, we try dividing 347,132,845 by 3:
347,132,845 ÷ 3 = 115,710,948.3333
If the quotient is a whole number, then 3 and 115,710,948.3333 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 | 347,132,845 | |
| -1 | -347,132,845 |
Let's try dividing by 4:
347,132,845 ÷ 4 = 86,783,211.25
If the quotient is a whole number, then 4 and 86,783,211.25 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 | 347,132,845 | |
| -1 | 347,132,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 109 | 355 | 545 | 7,739 | 8,971 | 38,695 | 44,855 | 636,941 | 977,839 | 3,184,705 | 4,889,195 | 69,426,569 | 347,132,845 |
| -1 | -5 | -71 | -109 | -355 | -545 | -7,739 | -8,971 | -38,695 | -44,855 | -636,941 | -977,839 | -3,184,705 | -4,889,195 | -69,426,569 | -347,132,845 |
