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 260,573,845, 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 | 260,573,845 | |
| -1 | -260,573,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,573,845.
Example:
1 x 260,573,845 = 260,573,845
and
-1 x -260,573,845 = 260,573,845
Notice both answers equal 260,573,845
With that explanation out of the way, let's continue. Next, we take the number 260,573,845 and divide it by 2:
260,573,845 ÷ 2 = 130,286,922.5
If the quotient is a whole number, then 2 and 130,286,922.5 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 | 260,573,845 | |
| -1 | -260,573,845 |
Now, we try dividing 260,573,845 by 3:
260,573,845 ÷ 3 = 86,857,948.3333
If the quotient is a whole number, then 3 and 86,857,948.3333 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 | 260,573,845 | |
| -1 | -260,573,845 |
Let's try dividing by 4:
260,573,845 ÷ 4 = 65,143,461.25
If the quotient is a whole number, then 4 and 65,143,461.25 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 | 260,573,845 | |
| -1 | 260,573,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 256,723 | 1,283,615 | 1,797,061 | 7,444,967 | 8,985,305 | 37,224,835 | 52,114,769 | 260,573,845 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -256,723 | -1,283,615 | -1,797,061 | -7,444,967 | -8,985,305 | -37,224,835 | -52,114,769 | -260,573,845 |
