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 352,714,747, 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 | 352,714,747 | |
| -1 | -352,714,747 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 352,714,747.
Example:
1 x 352,714,747 = 352,714,747
and
-1 x -352,714,747 = 352,714,747
Notice both answers equal 352,714,747
With that explanation out of the way, let's continue. Next, we take the number 352,714,747 and divide it by 2:
352,714,747 ÷ 2 = 176,357,373.5
If the quotient is a whole number, then 2 and 176,357,373.5 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 | 352,714,747 | |
| -1 | -352,714,747 |
Now, we try dividing 352,714,747 by 3:
352,714,747 ÷ 3 = 117,571,582.3333
If the quotient is a whole number, then 3 and 117,571,582.3333 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 | 352,714,747 | |
| -1 | -352,714,747 |
Let's try dividing by 4:
352,714,747 ÷ 4 = 88,178,686.75
If the quotient is a whole number, then 4 and 88,178,686.75 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 | 352,714,747 | |
| -1 | 352,714,747 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 37 | 77 | 259 | 407 | 2,849 | 123,803 | 866,621 | 1,361,833 | 4,580,711 | 9,532,831 | 32,064,977 | 50,387,821 | 352,714,747 |
| -1 | -7 | -11 | -37 | -77 | -259 | -407 | -2,849 | -123,803 | -866,621 | -1,361,833 | -4,580,711 | -9,532,831 | -32,064,977 | -50,387,821 | -352,714,747 |
