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 351,738,625, 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 | 351,738,625 | |
| -1 | -351,738,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,738,625.
Example:
1 x 351,738,625 = 351,738,625
and
-1 x -351,738,625 = 351,738,625
Notice both answers equal 351,738,625
With that explanation out of the way, let's continue. Next, we take the number 351,738,625 and divide it by 2:
351,738,625 ÷ 2 = 175,869,312.5
If the quotient is a whole number, then 2 and 175,869,312.5 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 | 351,738,625 | |
| -1 | -351,738,625 |
Now, we try dividing 351,738,625 by 3:
351,738,625 ÷ 3 = 117,246,208.3333
If the quotient is a whole number, then 3 and 117,246,208.3333 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 | 351,738,625 | |
| -1 | -351,738,625 |
Let's try dividing by 4:
351,738,625 ÷ 4 = 87,934,656.25
If the quotient is a whole number, then 4 and 87,934,656.25 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 | 351,738,625 | |
| -1 | 351,738,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 401,987 | 2,009,935 | 2,813,909 | 10,049,675 | 14,069,545 | 50,248,375 | 70,347,725 | 351,738,625 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -401,987 | -2,009,935 | -2,813,909 | -10,049,675 | -14,069,545 | -50,248,375 | -70,347,725 | -351,738,625 |
