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 153,010,895, 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 | 153,010,895 | |
| -1 | -153,010,895 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,010,895.
Example:
1 x 153,010,895 = 153,010,895
and
-1 x -153,010,895 = 153,010,895
Notice both answers equal 153,010,895
With that explanation out of the way, let's continue. Next, we take the number 153,010,895 and divide it by 2:
153,010,895 ÷ 2 = 76,505,447.5
If the quotient is a whole number, then 2 and 76,505,447.5 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 | 153,010,895 | |
| -1 | -153,010,895 |
Now, we try dividing 153,010,895 by 3:
153,010,895 ÷ 3 = 51,003,631.6667
If the quotient is a whole number, then 3 and 51,003,631.6667 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 | 153,010,895 | |
| -1 | -153,010,895 |
Let's try dividing by 4:
153,010,895 ÷ 4 = 38,252,723.75
If the quotient is a whole number, then 4 and 38,252,723.75 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 | 153,010,895 | |
| -1 | 153,010,895 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 59 | 95 | 295 | 1,121 | 5,605 | 27,299 | 136,495 | 518,681 | 1,610,641 | 2,593,405 | 8,053,205 | 30,602,179 | 153,010,895 |
| -1 | -5 | -19 | -59 | -95 | -295 | -1,121 | -5,605 | -27,299 | -136,495 | -518,681 | -1,610,641 | -2,593,405 | -8,053,205 | -30,602,179 | -153,010,895 |
