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 153,130,237, 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 | 153,130,237 | |
| -1 | -153,130,237 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,130,237.
Example:
1 x 153,130,237 = 153,130,237
and
-1 x -153,130,237 = 153,130,237
Notice both answers equal 153,130,237
With that explanation out of the way, let's continue. Next, we take the number 153,130,237 and divide it by 2:
153,130,237 ÷ 2 = 76,565,118.5
If the quotient is a whole number, then 2 and 76,565,118.5 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 | 153,130,237 | |
| -1 | -153,130,237 |
Now, we try dividing 153,130,237 by 3:
153,130,237 ÷ 3 = 51,043,412.3333
If the quotient is a whole number, then 3 and 51,043,412.3333 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 | 153,130,237 | |
| -1 | -153,130,237 |
Let's try dividing by 4:
153,130,237 ÷ 4 = 38,282,559.25
If the quotient is a whole number, then 4 and 38,282,559.25 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 | 153,130,237 | |
| -1 | 153,130,237 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 29 | 221 | 377 | 493 | 6,409 | 23,893 | 310,609 | 406,181 | 692,897 | 5,280,353 | 9,007,661 | 11,779,249 | 153,130,237 |
| -1 | -13 | -17 | -29 | -221 | -377 | -493 | -6,409 | -23,893 | -310,609 | -406,181 | -692,897 | -5,280,353 | -9,007,661 | -11,779,249 | -153,130,237 |
