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 347,280,631, 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 | 347,280,631 | |
| -1 | -347,280,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 347,280,631.
Example:
1 x 347,280,631 = 347,280,631
and
-1 x -347,280,631 = 347,280,631
Notice both answers equal 347,280,631
With that explanation out of the way, let's continue. Next, we take the number 347,280,631 and divide it by 2:
347,280,631 ÷ 2 = 173,640,315.5
If the quotient is a whole number, then 2 and 173,640,315.5 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 | 347,280,631 | |
| -1 | -347,280,631 |
Now, we try dividing 347,280,631 by 3:
347,280,631 ÷ 3 = 115,760,210.3333
If the quotient is a whole number, then 3 and 115,760,210.3333 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 | 347,280,631 | |
| -1 | -347,280,631 |
Let's try dividing by 4:
347,280,631 ÷ 4 = 86,820,157.75
If the quotient is a whole number, then 4 and 86,820,157.75 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 | 347,280,631 | |
| -1 | 347,280,631 |
If you did it right, you will end up with this table:
| 1 | 31 | 37 | 67 | 1,147 | 2,077 | 2,479 | 4,519 | 76,849 | 140,089 | 167,203 | 302,773 | 5,183,293 | 9,385,963 | 11,202,601 | 347,280,631 |
| -1 | -31 | -37 | -67 | -1,147 | -2,077 | -2,479 | -4,519 | -76,849 | -140,089 | -167,203 | -302,773 | -5,183,293 | -9,385,963 | -11,202,601 | -347,280,631 |
