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 250,371,035, 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 | 250,371,035 | |
| -1 | -250,371,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,371,035.
Example:
1 x 250,371,035 = 250,371,035
and
-1 x -250,371,035 = 250,371,035
Notice both answers equal 250,371,035
With that explanation out of the way, let's continue. Next, we take the number 250,371,035 and divide it by 2:
250,371,035 ÷ 2 = 125,185,517.5
If the quotient is a whole number, then 2 and 125,185,517.5 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 | 250,371,035 | |
| -1 | -250,371,035 |
Now, we try dividing 250,371,035 by 3:
250,371,035 ÷ 3 = 83,457,011.6667
If the quotient is a whole number, then 3 and 83,457,011.6667 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 | 250,371,035 | |
| -1 | -250,371,035 |
Let's try dividing by 4:
250,371,035 ÷ 4 = 62,592,758.75
If the quotient is a whole number, then 4 and 62,592,758.75 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 | 250,371,035 | |
| -1 | 250,371,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 1,259 | 1,283 | 6,295 | 6,415 | 39,029 | 39,773 | 195,145 | 198,865 | 1,615,297 | 8,076,485 | 50,074,207 | 250,371,035 |
| -1 | -5 | -31 | -155 | -1,259 | -1,283 | -6,295 | -6,415 | -39,029 | -39,773 | -195,145 | -198,865 | -1,615,297 | -8,076,485 | -50,074,207 | -250,371,035 |
