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 153,261,035, 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 | 153,261,035 | |
| -1 | -153,261,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,261,035.
Example:
1 x 153,261,035 = 153,261,035
and
-1 x -153,261,035 = 153,261,035
Notice both answers equal 153,261,035
With that explanation out of the way, let's continue. Next, we take the number 153,261,035 and divide it by 2:
153,261,035 ÷ 2 = 76,630,517.5
If the quotient is a whole number, then 2 and 76,630,517.5 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 | 153,261,035 | |
| -1 | -153,261,035 |
Now, we try dividing 153,261,035 by 3:
153,261,035 ÷ 3 = 51,087,011.6667
If the quotient is a whole number, then 3 and 51,087,011.6667 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 | 153,261,035 | |
| -1 | -153,261,035 |
Let's try dividing by 4:
153,261,035 ÷ 4 = 38,315,258.75
If the quotient is a whole number, then 4 and 38,315,258.75 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 | 153,261,035 | |
| -1 | 153,261,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 289 | 367 | 1,445 | 1,835 | 4,913 | 6,239 | 24,565 | 31,195 | 83,521 | 106,063 | 417,605 | 530,315 | 1,803,071 | 9,015,355 | 30,652,207 | 153,261,035 |
| -1 | -5 | -17 | -85 | -289 | -367 | -1,445 | -1,835 | -4,913 | -6,239 | -24,565 | -31,195 | -83,521 | -106,063 | -417,605 | -530,315 | -1,803,071 | -9,015,355 | -30,652,207 | -153,261,035 |
