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 160,323,425, 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 | 160,323,425 | |
| -1 | -160,323,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,323,425.
Example:
1 x 160,323,425 = 160,323,425
and
-1 x -160,323,425 = 160,323,425
Notice both answers equal 160,323,425
With that explanation out of the way, let's continue. Next, we take the number 160,323,425 and divide it by 2:
160,323,425 ÷ 2 = 80,161,712.5
If the quotient is a whole number, then 2 and 80,161,712.5 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 | 160,323,425 | |
| -1 | -160,323,425 |
Now, we try dividing 160,323,425 by 3:
160,323,425 ÷ 3 = 53,441,141.6667
If the quotient is a whole number, then 3 and 53,441,141.6667 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 | 160,323,425 | |
| -1 | -160,323,425 |
Let's try dividing by 4:
160,323,425 ÷ 4 = 40,080,856.25
If the quotient is a whole number, then 4 and 40,080,856.25 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 | 160,323,425 | |
| -1 | 160,323,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 173 | 475 | 865 | 1,951 | 3,287 | 4,325 | 9,755 | 16,435 | 37,069 | 48,775 | 82,175 | 185,345 | 337,523 | 926,725 | 1,687,615 | 6,412,937 | 8,438,075 | 32,064,685 | 160,323,425 |
| -1 | -5 | -19 | -25 | -95 | -173 | -475 | -865 | -1,951 | -3,287 | -4,325 | -9,755 | -16,435 | -37,069 | -48,775 | -82,175 | -185,345 | -337,523 | -926,725 | -1,687,615 | -6,412,937 | -8,438,075 | -32,064,685 | -160,323,425 |
