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 757,732,261, 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 | 757,732,261 | |
| -1 | -757,732,261 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 757,732,261.
Example:
1 x 757,732,261 = 757,732,261
and
-1 x -757,732,261 = 757,732,261
Notice both answers equal 757,732,261
With that explanation out of the way, let's continue. Next, we take the number 757,732,261 and divide it by 2:
757,732,261 ÷ 2 = 378,866,130.5
If the quotient is a whole number, then 2 and 378,866,130.5 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 | 757,732,261 | |
| -1 | -757,732,261 |
Now, we try dividing 757,732,261 by 3:
757,732,261 ÷ 3 = 252,577,420.3333
If the quotient is a whole number, then 3 and 252,577,420.3333 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 | 757,732,261 | |
| -1 | -757,732,261 |
Let's try dividing by 4:
757,732,261 ÷ 4 = 189,433,065.25
If the quotient is a whole number, then 4 and 189,433,065.25 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 | 757,732,261 | |
| -1 | 757,732,261 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 47 | 143 | 517 | 611 | 6,721 | 112,741 | 1,240,151 | 1,465,633 | 5,298,827 | 16,121,963 | 58,287,097 | 68,884,751 | 757,732,261 |
| -1 | -11 | -13 | -47 | -143 | -517 | -611 | -6,721 | -112,741 | -1,240,151 | -1,465,633 | -5,298,827 | -16,121,963 | -58,287,097 | -68,884,751 | -757,732,261 |
