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 376,828,705, 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 | 376,828,705 | |
| -1 | -376,828,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 376,828,705.
Example:
1 x 376,828,705 = 376,828,705
and
-1 x -376,828,705 = 376,828,705
Notice both answers equal 376,828,705
With that explanation out of the way, let's continue. Next, we take the number 376,828,705 and divide it by 2:
376,828,705 ÷ 2 = 188,414,352.5
If the quotient is a whole number, then 2 and 188,414,352.5 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 | 376,828,705 | |
| -1 | -376,828,705 |
Now, we try dividing 376,828,705 by 3:
376,828,705 ÷ 3 = 125,609,568.3333
If the quotient is a whole number, then 3 and 125,609,568.3333 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 | 376,828,705 | |
| -1 | -376,828,705 |
Let's try dividing by 4:
376,828,705 ÷ 4 = 94,207,176.25
If the quotient is a whole number, then 4 and 94,207,176.25 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 | 376,828,705 | |
| -1 | 376,828,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 131 | 655 | 1,441 | 7,205 | 52,301 | 261,505 | 575,311 | 2,876,555 | 6,851,431 | 34,257,155 | 75,365,741 | 376,828,705 |
| -1 | -5 | -11 | -55 | -131 | -655 | -1,441 | -7,205 | -52,301 | -261,505 | -575,311 | -2,876,555 | -6,851,431 | -34,257,155 | -75,365,741 | -376,828,705 |
