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 163,465,141, 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 | 163,465,141 | |
| -1 | -163,465,141 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,465,141.
Example:
1 x 163,465,141 = 163,465,141
and
-1 x -163,465,141 = 163,465,141
Notice both answers equal 163,465,141
With that explanation out of the way, let's continue. Next, we take the number 163,465,141 and divide it by 2:
163,465,141 ÷ 2 = 81,732,570.5
If the quotient is a whole number, then 2 and 81,732,570.5 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 | 163,465,141 | |
| -1 | -163,465,141 |
Now, we try dividing 163,465,141 by 3:
163,465,141 ÷ 3 = 54,488,380.3333
If the quotient is a whole number, then 3 and 54,488,380.3333 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 | 163,465,141 | |
| -1 | -163,465,141 |
Let's try dividing by 4:
163,465,141 ÷ 4 = 40,866,285.25
If the quotient is a whole number, then 4 and 40,866,285.25 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 | 163,465,141 | |
| -1 | 163,465,141 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 79 | 203 | 553 | 2,291 | 10,193 | 16,037 | 71,351 | 295,597 | 805,247 | 2,069,179 | 5,636,729 | 23,352,163 | 163,465,141 |
| -1 | -7 | -29 | -79 | -203 | -553 | -2,291 | -10,193 | -16,037 | -71,351 | -295,597 | -805,247 | -2,069,179 | -5,636,729 | -23,352,163 | -163,465,141 |
