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 354,132,443, 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 | 354,132,443 | |
| -1 | -354,132,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 354,132,443.
Example:
1 x 354,132,443 = 354,132,443
and
-1 x -354,132,443 = 354,132,443
Notice both answers equal 354,132,443
With that explanation out of the way, let's continue. Next, we take the number 354,132,443 and divide it by 2:
354,132,443 ÷ 2 = 177,066,221.5
If the quotient is a whole number, then 2 and 177,066,221.5 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 | 354,132,443 | |
| -1 | -354,132,443 |
Now, we try dividing 354,132,443 by 3:
354,132,443 ÷ 3 = 118,044,147.6667
If the quotient is a whole number, then 3 and 118,044,147.6667 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 | 354,132,443 | |
| -1 | -354,132,443 |
Let's try dividing by 4:
354,132,443 ÷ 4 = 88,533,110.75
If the quotient is a whole number, then 4 and 88,533,110.75 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 | 354,132,443 | |
| -1 | 354,132,443 |
If you did it right, you will end up with this table:
| 1 | 7 | 107 | 431 | 749 | 1,097 | 3,017 | 7,679 | 46,117 | 117,379 | 322,819 | 472,807 | 821,653 | 3,309,649 | 50,590,349 | 354,132,443 |
| -1 | -7 | -107 | -431 | -749 | -1,097 | -3,017 | -7,679 | -46,117 | -117,379 | -322,819 | -472,807 | -821,653 | -3,309,649 | -50,590,349 | -354,132,443 |
