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 160,124,825, 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 | 160,124,825 | |
| -1 | -160,124,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,124,825.
Example:
1 x 160,124,825 = 160,124,825
and
-1 x -160,124,825 = 160,124,825
Notice both answers equal 160,124,825
With that explanation out of the way, let's continue. Next, we take the number 160,124,825 and divide it by 2:
160,124,825 ÷ 2 = 80,062,412.5
If the quotient is a whole number, then 2 and 80,062,412.5 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 | 160,124,825 | |
| -1 | -160,124,825 |
Now, we try dividing 160,124,825 by 3:
160,124,825 ÷ 3 = 53,374,941.6667
If the quotient is a whole number, then 3 and 53,374,941.6667 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 | 160,124,825 | |
| -1 | -160,124,825 |
Let's try dividing by 4:
160,124,825 ÷ 4 = 40,031,206.25
If the quotient is a whole number, then 4 and 40,031,206.25 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 | 160,124,825 | |
| -1 | 160,124,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 593 | 1,543 | 2,965 | 4,151 | 7,715 | 10,801 | 14,825 | 20,755 | 38,575 | 54,005 | 103,775 | 270,025 | 914,999 | 4,574,995 | 6,404,993 | 22,874,975 | 32,024,965 | 160,124,825 |
| -1 | -5 | -7 | -25 | -35 | -175 | -593 | -1,543 | -2,965 | -4,151 | -7,715 | -10,801 | -14,825 | -20,755 | -38,575 | -54,005 | -103,775 | -270,025 | -914,999 | -4,574,995 | -6,404,993 | -22,874,975 | -32,024,965 | -160,124,825 |
