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 153,064,153, 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 | 153,064,153 | |
| -1 | -153,064,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,064,153.
Example:
1 x 153,064,153 = 153,064,153
and
-1 x -153,064,153 = 153,064,153
Notice both answers equal 153,064,153
With that explanation out of the way, let's continue. Next, we take the number 153,064,153 and divide it by 2:
153,064,153 ÷ 2 = 76,532,076.5
If the quotient is a whole number, then 2 and 76,532,076.5 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 | 153,064,153 | |
| -1 | -153,064,153 |
Now, we try dividing 153,064,153 by 3:
153,064,153 ÷ 3 = 51,021,384.3333
If the quotient is a whole number, then 3 and 51,021,384.3333 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 | 153,064,153 | |
| -1 | -153,064,153 |
Let's try dividing by 4:
153,064,153 ÷ 4 = 38,266,038.25
If the quotient is a whole number, then 4 and 38,266,038.25 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 | 153,064,153 | |
| -1 | 153,064,153 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 121 | 179 | 191 | 407 | 1,969 | 2,101 | 4,477 | 6,623 | 7,067 | 21,659 | 23,111 | 34,189 | 72,853 | 77,737 | 376,079 | 801,383 | 855,107 | 1,264,993 | 4,136,869 | 13,914,923 | 153,064,153 |
| -1 | -11 | -37 | -121 | -179 | -191 | -407 | -1,969 | -2,101 | -4,477 | -6,623 | -7,067 | -21,659 | -23,111 | -34,189 | -72,853 | -77,737 | -376,079 | -801,383 | -855,107 | -1,264,993 | -4,136,869 | -13,914,923 | -153,064,153 |
