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 341,343,415, 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 | 341,343,415 | |
| -1 | -341,343,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 341,343,415.
Example:
1 x 341,343,415 = 341,343,415
and
-1 x -341,343,415 = 341,343,415
Notice both answers equal 341,343,415
With that explanation out of the way, let's continue. Next, we take the number 341,343,415 and divide it by 2:
341,343,415 ÷ 2 = 170,671,707.5
If the quotient is a whole number, then 2 and 170,671,707.5 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 | 341,343,415 | |
| -1 | -341,343,415 |
Now, we try dividing 341,343,415 by 3:
341,343,415 ÷ 3 = 113,781,138.3333
If the quotient is a whole number, then 3 and 113,781,138.3333 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 | 341,343,415 | |
| -1 | -341,343,415 |
Let's try dividing by 4:
341,343,415 ÷ 4 = 85,335,853.75
If the quotient is a whole number, then 4 and 85,335,853.75 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 | 341,343,415 | |
| -1 | 341,343,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 607 | 3,035 | 4,249 | 16,067 | 21,245 | 80,335 | 112,469 | 562,345 | 9,752,669 | 48,763,345 | 68,268,683 | 341,343,415 |
| -1 | -5 | -7 | -35 | -607 | -3,035 | -4,249 | -16,067 | -21,245 | -80,335 | -112,469 | -562,345 | -9,752,669 | -48,763,345 | -68,268,683 | -341,343,415 |
