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 375,038,455, 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 | 375,038,455 | |
| -1 | -375,038,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 375,038,455.
Example:
1 x 375,038,455 = 375,038,455
and
-1 x -375,038,455 = 375,038,455
Notice both answers equal 375,038,455
With that explanation out of the way, let's continue. Next, we take the number 375,038,455 and divide it by 2:
375,038,455 ÷ 2 = 187,519,227.5
If the quotient is a whole number, then 2 and 187,519,227.5 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 | 375,038,455 | |
| -1 | -375,038,455 |
Now, we try dividing 375,038,455 by 3:
375,038,455 ÷ 3 = 125,012,818.3333
If the quotient is a whole number, then 3 and 125,012,818.3333 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 | 375,038,455 | |
| -1 | -375,038,455 |
Let's try dividing by 4:
375,038,455 ÷ 4 = 93,759,613.75
If the quotient is a whole number, then 4 and 93,759,613.75 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 | 375,038,455 | |
| -1 | 375,038,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 269 | 1,345 | 2,959 | 14,795 | 25,349 | 126,745 | 278,839 | 1,394,195 | 6,818,881 | 34,094,405 | 75,007,691 | 375,038,455 |
| -1 | -5 | -11 | -55 | -269 | -1,345 | -2,959 | -14,795 | -25,349 | -126,745 | -278,839 | -1,394,195 | -6,818,881 | -34,094,405 | -75,007,691 | -375,038,455 |
