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 163,202,501, 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 | 163,202,501 | |
| -1 | -163,202,501 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,202,501.
Example:
1 x 163,202,501 = 163,202,501
and
-1 x -163,202,501 = 163,202,501
Notice both answers equal 163,202,501
With that explanation out of the way, let's continue. Next, we take the number 163,202,501 and divide it by 2:
163,202,501 ÷ 2 = 81,601,250.5
If the quotient is a whole number, then 2 and 81,601,250.5 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 | 163,202,501 | |
| -1 | -163,202,501 |
Now, we try dividing 163,202,501 by 3:
163,202,501 ÷ 3 = 54,400,833.6667
If the quotient is a whole number, then 3 and 54,400,833.6667 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 | 163,202,501 | |
| -1 | -163,202,501 |
Let's try dividing by 4:
163,202,501 ÷ 4 = 40,800,625.25
If the quotient is a whole number, then 4 and 40,800,625.25 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 | 163,202,501 | |
| -1 | 163,202,501 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 43 | 77 | 121 | 301 | 473 | 847 | 3,311 | 4,481 | 5,203 | 31,367 | 36,421 | 49,291 | 192,683 | 345,037 | 542,201 | 1,348,781 | 2,119,513 | 3,795,407 | 14,836,591 | 23,314,643 | 163,202,501 |
| -1 | -7 | -11 | -43 | -77 | -121 | -301 | -473 | -847 | -3,311 | -4,481 | -5,203 | -31,367 | -36,421 | -49,291 | -192,683 | -345,037 | -542,201 | -1,348,781 | -2,119,513 | -3,795,407 | -14,836,591 | -23,314,643 | -163,202,501 |
