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 351,144,661, 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 | 351,144,661 | |
| -1 | -351,144,661 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,144,661.
Example:
1 x 351,144,661 = 351,144,661
and
-1 x -351,144,661 = 351,144,661
Notice both answers equal 351,144,661
With that explanation out of the way, let's continue. Next, we take the number 351,144,661 and divide it by 2:
351,144,661 ÷ 2 = 175,572,330.5
If the quotient is a whole number, then 2 and 175,572,330.5 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 | 351,144,661 | |
| -1 | -351,144,661 |
Now, we try dividing 351,144,661 by 3:
351,144,661 ÷ 3 = 117,048,220.3333
If the quotient is a whole number, then 3 and 117,048,220.3333 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 | 351,144,661 | |
| -1 | -351,144,661 |
Let's try dividing by 4:
351,144,661 ÷ 4 = 87,786,165.25
If the quotient is a whole number, then 4 and 87,786,165.25 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 | 351,144,661 | |
| -1 | 351,144,661 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 329 | 877 | 1,217 | 6,139 | 8,519 | 41,219 | 57,199 | 288,533 | 400,393 | 1,067,309 | 7,471,163 | 50,163,523 | 351,144,661 |
| -1 | -7 | -47 | -329 | -877 | -1,217 | -6,139 | -8,519 | -41,219 | -57,199 | -288,533 | -400,393 | -1,067,309 | -7,471,163 | -50,163,523 | -351,144,661 |
