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 352,061,143, 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 | 352,061,143 | |
| -1 | -352,061,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 352,061,143.
Example:
1 x 352,061,143 = 352,061,143
and
-1 x -352,061,143 = 352,061,143
Notice both answers equal 352,061,143
With that explanation out of the way, let's continue. Next, we take the number 352,061,143 and divide it by 2:
352,061,143 ÷ 2 = 176,030,571.5
If the quotient is a whole number, then 2 and 176,030,571.5 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 | 352,061,143 | |
| -1 | -352,061,143 |
Now, we try dividing 352,061,143 by 3:
352,061,143 ÷ 3 = 117,353,714.3333
If the quotient is a whole number, then 3 and 117,353,714.3333 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 | 352,061,143 | |
| -1 | -352,061,143 |
Let's try dividing by 4:
352,061,143 ÷ 4 = 88,015,285.75
If the quotient is a whole number, then 4 and 88,015,285.75 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 | 352,061,143 | |
| -1 | 352,061,143 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 193 | 1,351 | 3,281 | 15,329 | 22,967 | 107,303 | 260,593 | 1,824,151 | 2,958,497 | 20,709,479 | 50,294,449 | 352,061,143 |
| -1 | -7 | -17 | -119 | -193 | -1,351 | -3,281 | -15,329 | -22,967 | -107,303 | -260,593 | -1,824,151 | -2,958,497 | -20,709,479 | -50,294,449 | -352,061,143 |
