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 343,534,625, 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 | 343,534,625 | |
| -1 | -343,534,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 343,534,625.
Example:
1 x 343,534,625 = 343,534,625
and
-1 x -343,534,625 = 343,534,625
Notice both answers equal 343,534,625
With that explanation out of the way, let's continue. Next, we take the number 343,534,625 and divide it by 2:
343,534,625 ÷ 2 = 171,767,312.5
If the quotient is a whole number, then 2 and 171,767,312.5 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 | 343,534,625 | |
| -1 | -343,534,625 |
Now, we try dividing 343,534,625 by 3:
343,534,625 ÷ 3 = 114,511,541.6667
If the quotient is a whole number, then 3 and 114,511,541.6667 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 | 343,534,625 | |
| -1 | -343,534,625 |
Let's try dividing by 4:
343,534,625 ÷ 4 = 85,883,656.25
If the quotient is a whole number, then 4 and 85,883,656.25 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 | 343,534,625 | |
| -1 | 343,534,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 392,611 | 1,963,055 | 2,748,277 | 9,815,275 | 13,741,385 | 49,076,375 | 68,706,925 | 343,534,625 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -392,611 | -1,963,055 | -2,748,277 | -9,815,275 | -13,741,385 | -49,076,375 | -68,706,925 | -343,534,625 |
