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 351,002,365, 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 | 351,002,365 | |
| -1 | -351,002,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,002,365.
Example:
1 x 351,002,365 = 351,002,365
and
-1 x -351,002,365 = 351,002,365
Notice both answers equal 351,002,365
With that explanation out of the way, let's continue. Next, we take the number 351,002,365 and divide it by 2:
351,002,365 ÷ 2 = 175,501,182.5
If the quotient is a whole number, then 2 and 175,501,182.5 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 | 351,002,365 | |
| -1 | -351,002,365 |
Now, we try dividing 351,002,365 by 3:
351,002,365 ÷ 3 = 117,000,788.3333
If the quotient is a whole number, then 3 and 117,000,788.3333 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 | 351,002,365 | |
| -1 | -351,002,365 |
Let's try dividing by 4:
351,002,365 ÷ 4 = 87,750,591.25
If the quotient is a whole number, then 4 and 87,750,591.25 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 | 351,002,365 | |
| -1 | 351,002,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,279 | 6,395 | 7,841 | 8,953 | 39,205 | 44,765 | 54,887 | 274,435 | 10,028,639 | 50,143,195 | 70,200,473 | 351,002,365 |
| -1 | -5 | -7 | -35 | -1,279 | -6,395 | -7,841 | -8,953 | -39,205 | -44,765 | -54,887 | -274,435 | -10,028,639 | -50,143,195 | -70,200,473 | -351,002,365 |
