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 37,493,143, 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 | 37,493,143 | |
| -1 | -37,493,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,493,143.
Example:
1 x 37,493,143 = 37,493,143
and
-1 x -37,493,143 = 37,493,143
Notice both answers equal 37,493,143
With that explanation out of the way, let's continue. Next, we take the number 37,493,143 and divide it by 2:
37,493,143 ÷ 2 = 18,746,571.5
If the quotient is a whole number, then 2 and 18,746,571.5 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 | 37,493,143 | |
| -1 | -37,493,143 |
Now, we try dividing 37,493,143 by 3:
37,493,143 ÷ 3 = 12,497,714.3333
If the quotient is a whole number, then 3 and 12,497,714.3333 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 | 37,493,143 | |
| -1 | -37,493,143 |
Let's try dividing by 4:
37,493,143 ÷ 4 = 9,373,285.75
If the quotient is a whole number, then 4 and 9,373,285.75 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 | 37,493,143 | |
| -1 | 37,493,143 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 59 | 493 | 1,003 | 1,289 | 1,711 | 21,913 | 29,087 | 37,381 | 76,051 | 635,477 | 1,292,867 | 2,205,479 | 37,493,143 |
| -1 | -17 | -29 | -59 | -493 | -1,003 | -1,289 | -1,711 | -21,913 | -29,087 | -37,381 | -76,051 | -635,477 | -1,292,867 | -2,205,479 | -37,493,143 |
