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 375,000,647, 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 | 375,000,647 | |
| -1 | -375,000,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 375,000,647.
Example:
1 x 375,000,647 = 375,000,647
and
-1 x -375,000,647 = 375,000,647
Notice both answers equal 375,000,647
With that explanation out of the way, let's continue. Next, we take the number 375,000,647 and divide it by 2:
375,000,647 ÷ 2 = 187,500,323.5
If the quotient is a whole number, then 2 and 187,500,323.5 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 | 375,000,647 | |
| -1 | -375,000,647 |
Now, we try dividing 375,000,647 by 3:
375,000,647 ÷ 3 = 125,000,215.6667
If the quotient is a whole number, then 3 and 125,000,215.6667 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 | 375,000,647 | |
| -1 | -375,000,647 |
Let's try dividing by 4:
375,000,647 ÷ 4 = 93,750,161.75
If the quotient is a whole number, then 4 and 93,750,161.75 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 | 375,000,647 | |
| -1 | 375,000,647 |
If you did it right, you will end up with this table:
| 1 | 7 | 127 | 137 | 889 | 959 | 3,079 | 17,399 | 21,553 | 121,793 | 391,033 | 421,823 | 2,737,231 | 2,952,761 | 53,571,521 | 375,000,647 |
| -1 | -7 | -127 | -137 | -889 | -959 | -3,079 | -17,399 | -21,553 | -121,793 | -391,033 | -421,823 | -2,737,231 | -2,952,761 | -53,571,521 | -375,000,647 |
