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 350,132,515, 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 | 350,132,515 | |
| -1 | -350,132,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 350,132,515.
Example:
1 x 350,132,515 = 350,132,515
and
-1 x -350,132,515 = 350,132,515
Notice both answers equal 350,132,515
With that explanation out of the way, let's continue. Next, we take the number 350,132,515 and divide it by 2:
350,132,515 ÷ 2 = 175,066,257.5
If the quotient is a whole number, then 2 and 175,066,257.5 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 | 350,132,515 | |
| -1 | -350,132,515 |
Now, we try dividing 350,132,515 by 3:
350,132,515 ÷ 3 = 116,710,838.3333
If the quotient is a whole number, then 3 and 116,710,838.3333 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 | 350,132,515 | |
| -1 | -350,132,515 |
Let's try dividing by 4:
350,132,515 ÷ 4 = 87,533,128.75
If the quotient is a whole number, then 4 and 87,533,128.75 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 | 350,132,515 | |
| -1 | 350,132,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 563 | 2,815 | 4,289 | 16,327 | 21,445 | 81,635 | 124,381 | 621,905 | 2,414,707 | 12,073,535 | 70,026,503 | 350,132,515 |
| -1 | -5 | -29 | -145 | -563 | -2,815 | -4,289 | -16,327 | -21,445 | -81,635 | -124,381 | -621,905 | -2,414,707 | -12,073,535 | -70,026,503 | -350,132,515 |
