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 361,404,757, 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 | 361,404,757 | |
| -1 | -361,404,757 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 361,404,757.
Example:
1 x 361,404,757 = 361,404,757
and
-1 x -361,404,757 = 361,404,757
Notice both answers equal 361,404,757
With that explanation out of the way, let's continue. Next, we take the number 361,404,757 and divide it by 2:
361,404,757 ÷ 2 = 180,702,378.5
If the quotient is a whole number, then 2 and 180,702,378.5 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 | 361,404,757 | |
| -1 | -361,404,757 |
Now, we try dividing 361,404,757 by 3:
361,404,757 ÷ 3 = 120,468,252.3333
If the quotient is a whole number, then 3 and 120,468,252.3333 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 | 361,404,757 | |
| -1 | -361,404,757 |
Let's try dividing by 4:
361,404,757 ÷ 4 = 90,351,189.25
If the quotient is a whole number, then 4 and 90,351,189.25 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 | 361,404,757 | |
| -1 | 361,404,757 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 29 | 133 | 203 | 551 | 3,857 | 93,701 | 655,907 | 1,780,319 | 2,717,329 | 12,462,233 | 19,021,303 | 51,629,251 | 361,404,757 |
| -1 | -7 | -19 | -29 | -133 | -203 | -551 | -3,857 | -93,701 | -655,907 | -1,780,319 | -2,717,329 | -12,462,233 | -19,021,303 | -51,629,251 | -361,404,757 |
