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 32,351,275, 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 | 32,351,275 | |
| -1 | -32,351,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,351,275.
Example:
1 x 32,351,275 = 32,351,275
and
-1 x -32,351,275 = 32,351,275
Notice both answers equal 32,351,275
With that explanation out of the way, let's continue. Next, we take the number 32,351,275 and divide it by 2:
32,351,275 ÷ 2 = 16,175,637.5
If the quotient is a whole number, then 2 and 16,175,637.5 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 | 32,351,275 | |
| -1 | -32,351,275 |
Now, we try dividing 32,351,275 by 3:
32,351,275 ÷ 3 = 10,783,758.3333
If the quotient is a whole number, then 3 and 10,783,758.3333 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 | 32,351,275 | |
| -1 | -32,351,275 |
Let's try dividing by 4:
32,351,275 ÷ 4 = 8,087,818.75
If the quotient is a whole number, then 4 and 8,087,818.75 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 | 32,351,275 | |
| -1 | 32,351,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 47 | 55 | 235 | 275 | 517 | 1,175 | 2,503 | 2,585 | 12,515 | 12,925 | 27,533 | 62,575 | 117,641 | 137,665 | 588,205 | 688,325 | 1,294,051 | 2,941,025 | 6,470,255 | 32,351,275 |
| -1 | -5 | -11 | -25 | -47 | -55 | -235 | -275 | -517 | -1,175 | -2,503 | -2,585 | -12,515 | -12,925 | -27,533 | -62,575 | -117,641 | -137,665 | -588,205 | -688,325 | -1,294,051 | -2,941,025 | -6,470,255 | -32,351,275 |
