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 153,655,355, 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 | 153,655,355 | |
| -1 | -153,655,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,655,355.
Example:
1 x 153,655,355 = 153,655,355
and
-1 x -153,655,355 = 153,655,355
Notice both answers equal 153,655,355
With that explanation out of the way, let's continue. Next, we take the number 153,655,355 and divide it by 2:
153,655,355 ÷ 2 = 76,827,677.5
If the quotient is a whole number, then 2 and 76,827,677.5 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 | 153,655,355 | |
| -1 | -153,655,355 |
Now, we try dividing 153,655,355 by 3:
153,655,355 ÷ 3 = 51,218,451.6667
If the quotient is a whole number, then 3 and 51,218,451.6667 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 | 153,655,355 | |
| -1 | -153,655,355 |
Let's try dividing by 4:
153,655,355 ÷ 4 = 38,413,838.75
If the quotient is a whole number, then 4 and 38,413,838.75 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 | 153,655,355 | |
| -1 | 153,655,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,597 | 2,749 | 7,985 | 11,179 | 13,745 | 19,243 | 55,895 | 96,215 | 4,390,153 | 21,950,765 | 30,731,071 | 153,655,355 |
| -1 | -5 | -7 | -35 | -1,597 | -2,749 | -7,985 | -11,179 | -13,745 | -19,243 | -55,895 | -96,215 | -4,390,153 | -21,950,765 | -30,731,071 | -153,655,355 |
