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 577,155,457, 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 | 577,155,457 | |
| -1 | -577,155,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 577,155,457.
Example:
1 x 577,155,457 = 577,155,457
and
-1 x -577,155,457 = 577,155,457
Notice both answers equal 577,155,457
With that explanation out of the way, let's continue. Next, we take the number 577,155,457 and divide it by 2:
577,155,457 ÷ 2 = 288,577,728.5
If the quotient is a whole number, then 2 and 288,577,728.5 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 | 577,155,457 | |
| -1 | -577,155,457 |
Now, we try dividing 577,155,457 by 3:
577,155,457 ÷ 3 = 192,385,152.3333
If the quotient is a whole number, then 3 and 192,385,152.3333 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 | 577,155,457 | |
| -1 | -577,155,457 |
Let's try dividing by 4:
577,155,457 ÷ 4 = 144,288,864.25
If the quotient is a whole number, then 4 and 144,288,864.25 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 | 577,155,457 | |
| -1 | 577,155,457 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 323 | 937 | 1,907 | 15,929 | 17,803 | 32,419 | 36,233 | 302,651 | 615,961 | 1,786,859 | 30,376,603 | 33,950,321 | 577,155,457 |
| -1 | -17 | -19 | -323 | -937 | -1,907 | -15,929 | -17,803 | -32,419 | -36,233 | -302,651 | -615,961 | -1,786,859 | -30,376,603 | -33,950,321 | -577,155,457 |
