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 375,501,415, 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 | 375,501,415 | |
| -1 | -375,501,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 375,501,415.
Example:
1 x 375,501,415 = 375,501,415
and
-1 x -375,501,415 = 375,501,415
Notice both answers equal 375,501,415
With that explanation out of the way, let's continue. Next, we take the number 375,501,415 and divide it by 2:
375,501,415 ÷ 2 = 187,750,707.5
If the quotient is a whole number, then 2 and 187,750,707.5 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 | 375,501,415 | |
| -1 | -375,501,415 |
Now, we try dividing 375,501,415 by 3:
375,501,415 ÷ 3 = 125,167,138.3333
If the quotient is a whole number, then 3 and 125,167,138.3333 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 | 375,501,415 | |
| -1 | -375,501,415 |
Let's try dividing by 4:
375,501,415 ÷ 4 = 93,875,353.75
If the quotient is a whole number, then 4 and 93,875,353.75 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 | 375,501,415 | |
| -1 | 375,501,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 257 | 365 | 1,285 | 4,003 | 18,761 | 20,015 | 93,805 | 292,219 | 1,028,771 | 1,461,095 | 5,143,855 | 75,100,283 | 375,501,415 |
| -1 | -5 | -73 | -257 | -365 | -1,285 | -4,003 | -18,761 | -20,015 | -93,805 | -292,219 | -1,028,771 | -1,461,095 | -5,143,855 | -75,100,283 | -375,501,415 |
