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 163,000,025, 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 | 163,000,025 | |
| -1 | -163,000,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,000,025.
Example:
1 x 163,000,025 = 163,000,025
and
-1 x -163,000,025 = 163,000,025
Notice both answers equal 163,000,025
With that explanation out of the way, let's continue. Next, we take the number 163,000,025 and divide it by 2:
163,000,025 ÷ 2 = 81,500,012.5
If the quotient is a whole number, then 2 and 81,500,012.5 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 | 163,000,025 | |
| -1 | -163,000,025 |
Now, we try dividing 163,000,025 by 3:
163,000,025 ÷ 3 = 54,333,341.6667
If the quotient is a whole number, then 3 and 54,333,341.6667 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 | 163,000,025 | |
| -1 | -163,000,025 |
Let's try dividing by 4:
163,000,025 ÷ 4 = 40,750,006.25
If the quotient is a whole number, then 4 and 40,750,006.25 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 | 163,000,025 | |
| -1 | 163,000,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 71 | 131 | 355 | 655 | 701 | 1,775 | 3,275 | 3,505 | 9,301 | 17,525 | 46,505 | 49,771 | 91,831 | 232,525 | 248,855 | 459,155 | 1,244,275 | 2,295,775 | 6,520,001 | 32,600,005 | 163,000,025 |
| -1 | -5 | -25 | -71 | -131 | -355 | -655 | -701 | -1,775 | -3,275 | -3,505 | -9,301 | -17,525 | -46,505 | -49,771 | -91,831 | -232,525 | -248,855 | -459,155 | -1,244,275 | -2,295,775 | -6,520,001 | -32,600,005 | -163,000,025 |
