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 37,531,417, 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 | 37,531,417 | |
| -1 | -37,531,417 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,531,417.
Example:
1 x 37,531,417 = 37,531,417
and
-1 x -37,531,417 = 37,531,417
Notice both answers equal 37,531,417
With that explanation out of the way, let's continue. Next, we take the number 37,531,417 and divide it by 2:
37,531,417 ÷ 2 = 18,765,708.5
If the quotient is a whole number, then 2 and 18,765,708.5 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 | 37,531,417 | |
| -1 | -37,531,417 |
Now, we try dividing 37,531,417 by 3:
37,531,417 ÷ 3 = 12,510,472.3333
If the quotient is a whole number, then 3 and 12,510,472.3333 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 | 37,531,417 | |
| -1 | -37,531,417 |
Let's try dividing by 4:
37,531,417 ÷ 4 = 9,382,854.25
If the quotient is a whole number, then 4 and 9,382,854.25 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 | 37,531,417 | |
| -1 | 37,531,417 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 73 | 77 | 121 | 511 | 607 | 803 | 847 | 4,249 | 5,621 | 6,677 | 8,833 | 44,311 | 46,739 | 61,831 | 73,447 | 310,177 | 487,421 | 514,129 | 3,411,947 | 5,361,631 | 37,531,417 |
| -1 | -7 | -11 | -73 | -77 | -121 | -511 | -607 | -803 | -847 | -4,249 | -5,621 | -6,677 | -8,833 | -44,311 | -46,739 | -61,831 | -73,447 | -310,177 | -487,421 | -514,129 | -3,411,947 | -5,361,631 | -37,531,417 |
