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 32,157,671, 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 | 32,157,671 | |
| -1 | -32,157,671 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,157,671.
Example:
1 x 32,157,671 = 32,157,671
and
-1 x -32,157,671 = 32,157,671
Notice both answers equal 32,157,671
With that explanation out of the way, let's continue. Next, we take the number 32,157,671 and divide it by 2:
32,157,671 ÷ 2 = 16,078,835.5
If the quotient is a whole number, then 2 and 16,078,835.5 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 | 32,157,671 | |
| -1 | -32,157,671 |
Now, we try dividing 32,157,671 by 3:
32,157,671 ÷ 3 = 10,719,223.6667
If the quotient is a whole number, then 3 and 10,719,223.6667 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 | 32,157,671 | |
| -1 | -32,157,671 |
Let's try dividing by 4:
32,157,671 ÷ 4 = 8,039,417.75
If the quotient is a whole number, then 4 and 8,039,417.75 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 | 32,157,671 | |
| -1 | 32,157,671 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 49 | 91 | 133 | 247 | 637 | 931 | 1,729 | 2,657 | 12,103 | 18,599 | 34,541 | 50,483 | 130,193 | 241,787 | 353,381 | 656,279 | 1,692,509 | 2,473,667 | 4,593,953 | 32,157,671 |
| -1 | -7 | -13 | -19 | -49 | -91 | -133 | -247 | -637 | -931 | -1,729 | -2,657 | -12,103 | -18,599 | -34,541 | -50,483 | -130,193 | -241,787 | -353,381 | -656,279 | -1,692,509 | -2,473,667 | -4,593,953 | -32,157,671 |
