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 155,504,335, 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 | 155,504,335 | |
| -1 | -155,504,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 155,504,335.
Example:
1 x 155,504,335 = 155,504,335
and
-1 x -155,504,335 = 155,504,335
Notice both answers equal 155,504,335
With that explanation out of the way, let's continue. Next, we take the number 155,504,335 and divide it by 2:
155,504,335 ÷ 2 = 77,752,167.5
If the quotient is a whole number, then 2 and 77,752,167.5 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 | 155,504,335 | |
| -1 | -155,504,335 |
Now, we try dividing 155,504,335 by 3:
155,504,335 ÷ 3 = 51,834,778.3333
If the quotient is a whole number, then 3 and 51,834,778.3333 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 | 155,504,335 | |
| -1 | -155,504,335 |
Let's try dividing by 4:
155,504,335 ÷ 4 = 38,876,083.75
If the quotient is a whole number, then 4 and 38,876,083.75 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 | 155,504,335 | |
| -1 | 155,504,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 2,039 | 2,179 | 10,195 | 10,895 | 14,273 | 15,253 | 71,365 | 76,265 | 4,442,981 | 22,214,905 | 31,100,867 | 155,504,335 |
| -1 | -5 | -7 | -35 | -2,039 | -2,179 | -10,195 | -10,895 | -14,273 | -15,253 | -71,365 | -76,265 | -4,442,981 | -22,214,905 | -31,100,867 | -155,504,335 |
