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 247,766,575, 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 | 247,766,575 | |
| -1 | -247,766,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 247,766,575.
Example:
1 x 247,766,575 = 247,766,575
and
-1 x -247,766,575 = 247,766,575
Notice both answers equal 247,766,575
With that explanation out of the way, let's continue. Next, we take the number 247,766,575 and divide it by 2:
247,766,575 ÷ 2 = 123,883,287.5
If the quotient is a whole number, then 2 and 123,883,287.5 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 | 247,766,575 | |
| -1 | -247,766,575 |
Now, we try dividing 247,766,575 by 3:
247,766,575 ÷ 3 = 82,588,858.3333
If the quotient is a whole number, then 3 and 82,588,858.3333 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 | 247,766,575 | |
| -1 | -247,766,575 |
Let's try dividing by 4:
247,766,575 ÷ 4 = 61,941,643.75
If the quotient is a whole number, then 4 and 61,941,643.75 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 | 247,766,575 | |
| -1 | 247,766,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 29 | 35 | 145 | 175 | 203 | 725 | 1,015 | 5,075 | 48,821 | 244,105 | 341,747 | 1,220,525 | 1,415,809 | 1,708,735 | 7,079,045 | 8,543,675 | 9,910,663 | 35,395,225 | 49,553,315 | 247,766,575 |
| -1 | -5 | -7 | -25 | -29 | -35 | -145 | -175 | -203 | -725 | -1,015 | -5,075 | -48,821 | -244,105 | -341,747 | -1,220,525 | -1,415,809 | -1,708,735 | -7,079,045 | -8,543,675 | -9,910,663 | -35,395,225 | -49,553,315 | -247,766,575 |
