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 153,200,345, 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 | 153,200,345 | |
| -1 | -153,200,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,200,345.
Example:
1 x 153,200,345 = 153,200,345
and
-1 x -153,200,345 = 153,200,345
Notice both answers equal 153,200,345
With that explanation out of the way, let's continue. Next, we take the number 153,200,345 and divide it by 2:
153,200,345 ÷ 2 = 76,600,172.5
If the quotient is a whole number, then 2 and 76,600,172.5 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 | 153,200,345 | |
| -1 | -153,200,345 |
Now, we try dividing 153,200,345 by 3:
153,200,345 ÷ 3 = 51,066,781.6667
If the quotient is a whole number, then 3 and 51,066,781.6667 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 | 153,200,345 | |
| -1 | -153,200,345 |
Let's try dividing by 4:
153,200,345 ÷ 4 = 38,300,086.25
If the quotient is a whole number, then 4 and 38,300,086.25 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 | 153,200,345 | |
| -1 | 153,200,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 97 | 289 | 485 | 1,093 | 1,445 | 1,649 | 5,465 | 8,245 | 18,581 | 28,033 | 92,905 | 106,021 | 140,165 | 315,877 | 530,105 | 1,579,385 | 1,802,357 | 9,011,785 | 30,640,069 | 153,200,345 |
| -1 | -5 | -17 | -85 | -97 | -289 | -485 | -1,093 | -1,445 | -1,649 | -5,465 | -8,245 | -18,581 | -28,033 | -92,905 | -106,021 | -140,165 | -315,877 | -530,105 | -1,579,385 | -1,802,357 | -9,011,785 | -30,640,069 | -153,200,345 |
