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 352,776,319, 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 | 352,776,319 | |
| -1 | -352,776,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 352,776,319.
Example:
1 x 352,776,319 = 352,776,319
and
-1 x -352,776,319 = 352,776,319
Notice both answers equal 352,776,319
With that explanation out of the way, let's continue. Next, we take the number 352,776,319 and divide it by 2:
352,776,319 ÷ 2 = 176,388,159.5
If the quotient is a whole number, then 2 and 176,388,159.5 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 | 352,776,319 | |
| -1 | -352,776,319 |
Now, we try dividing 352,776,319 by 3:
352,776,319 ÷ 3 = 117,592,106.3333
If the quotient is a whole number, then 3 and 117,592,106.3333 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 | 352,776,319 | |
| -1 | -352,776,319 |
Let's try dividing by 4:
352,776,319 ÷ 4 = 88,194,079.75
If the quotient is a whole number, then 4 and 88,194,079.75 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 | 352,776,319 | |
| -1 | 352,776,319 |
If you did it right, you will end up with this table:
| 1 | 7 | 131 | 311 | 917 | 1,237 | 2,177 | 8,659 | 40,741 | 162,047 | 285,187 | 384,707 | 1,134,329 | 2,692,949 | 50,396,617 | 352,776,319 |
| -1 | -7 | -131 | -311 | -917 | -1,237 | -2,177 | -8,659 | -40,741 | -162,047 | -285,187 | -384,707 | -1,134,329 | -2,692,949 | -50,396,617 | -352,776,319 |
