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 36,472,163, 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 | 36,472,163 | |
| -1 | -36,472,163 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,472,163.
Example:
1 x 36,472,163 = 36,472,163
and
-1 x -36,472,163 = 36,472,163
Notice both answers equal 36,472,163
With that explanation out of the way, let's continue. Next, we take the number 36,472,163 and divide it by 2:
36,472,163 ÷ 2 = 18,236,081.5
If the quotient is a whole number, then 2 and 18,236,081.5 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 | 36,472,163 | |
| -1 | -36,472,163 |
Now, we try dividing 36,472,163 by 3:
36,472,163 ÷ 3 = 12,157,387.6667
If the quotient is a whole number, then 3 and 12,157,387.6667 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 | 36,472,163 | |
| -1 | -36,472,163 |
Let's try dividing by 4:
36,472,163 ÷ 4 = 9,118,040.75
If the quotient is a whole number, then 4 and 9,118,040.75 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 | 36,472,163 | |
| -1 | 36,472,163 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 109 | 763 | 1,417 | 3,677 | 9,919 | 25,739 | 47,801 | 334,607 | 400,793 | 2,805,551 | 5,210,309 | 36,472,163 |
| -1 | -7 | -13 | -91 | -109 | -763 | -1,417 | -3,677 | -9,919 | -25,739 | -47,801 | -334,607 | -400,793 | -2,805,551 | -5,210,309 | -36,472,163 |
