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 653,176,015, 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 | 653,176,015 | |
| -1 | -653,176,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 653,176,015.
Example:
1 x 653,176,015 = 653,176,015
and
-1 x -653,176,015 = 653,176,015
Notice both answers equal 653,176,015
With that explanation out of the way, let's continue. Next, we take the number 653,176,015 and divide it by 2:
653,176,015 ÷ 2 = 326,588,007.5
If the quotient is a whole number, then 2 and 326,588,007.5 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 | 653,176,015 | |
| -1 | -653,176,015 |
Now, we try dividing 653,176,015 by 3:
653,176,015 ÷ 3 = 217,725,338.3333
If the quotient is a whole number, then 3 and 217,725,338.3333 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 | 653,176,015 | |
| -1 | -653,176,015 |
Let's try dividing by 4:
653,176,015 ÷ 4 = 163,294,003.75
If the quotient is a whole number, then 4 and 163,294,003.75 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 | 653,176,015 | |
| -1 | 653,176,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 449 | 2,245 | 8,531 | 15,313 | 42,655 | 76,565 | 290,947 | 1,454,735 | 6,875,537 | 34,377,685 | 130,635,203 | 653,176,015 |
| -1 | -5 | -19 | -95 | -449 | -2,245 | -8,531 | -15,313 | -42,655 | -76,565 | -290,947 | -1,454,735 | -6,875,537 | -34,377,685 | -130,635,203 | -653,176,015 |
