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 352,422,155, 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 | 352,422,155 | |
| -1 | -352,422,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 352,422,155.
Example:
1 x 352,422,155 = 352,422,155
and
-1 x -352,422,155 = 352,422,155
Notice both answers equal 352,422,155
With that explanation out of the way, let's continue. Next, we take the number 352,422,155 and divide it by 2:
352,422,155 ÷ 2 = 176,211,077.5
If the quotient is a whole number, then 2 and 176,211,077.5 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 | 352,422,155 | |
| -1 | -352,422,155 |
Now, we try dividing 352,422,155 by 3:
352,422,155 ÷ 3 = 117,474,051.6667
If the quotient is a whole number, then 3 and 117,474,051.6667 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 | 352,422,155 | |
| -1 | -352,422,155 |
Let's try dividing by 4:
352,422,155 ÷ 4 = 88,105,538.75
If the quotient is a whole number, then 4 and 88,105,538.75 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 | 352,422,155 | |
| -1 | 352,422,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 107 | 535 | 1,819 | 9,095 | 38,749 | 193,745 | 658,733 | 3,293,665 | 4,146,143 | 20,730,715 | 70,484,431 | 352,422,155 |
| -1 | -5 | -17 | -85 | -107 | -535 | -1,819 | -9,095 | -38,749 | -193,745 | -658,733 | -3,293,665 | -4,146,143 | -20,730,715 | -70,484,431 | -352,422,155 |
