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 37,358,915, 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 | 37,358,915 | |
| -1 | -37,358,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,358,915.
Example:
1 x 37,358,915 = 37,358,915
and
-1 x -37,358,915 = 37,358,915
Notice both answers equal 37,358,915
With that explanation out of the way, let's continue. Next, we take the number 37,358,915 and divide it by 2:
37,358,915 ÷ 2 = 18,679,457.5
If the quotient is a whole number, then 2 and 18,679,457.5 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 | 37,358,915 | |
| -1 | -37,358,915 |
Now, we try dividing 37,358,915 by 3:
37,358,915 ÷ 3 = 12,452,971.6667
If the quotient is a whole number, then 3 and 12,452,971.6667 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 | 37,358,915 | |
| -1 | -37,358,915 |
Let's try dividing by 4:
37,358,915 ÷ 4 = 9,339,728.75
If the quotient is a whole number, then 4 and 9,339,728.75 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 | 37,358,915 | |
| -1 | 37,358,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 691 | 983 | 3,455 | 4,915 | 7,601 | 10,813 | 38,005 | 54,065 | 679,253 | 3,396,265 | 7,471,783 | 37,358,915 |
| -1 | -5 | -11 | -55 | -691 | -983 | -3,455 | -4,915 | -7,601 | -10,813 | -38,005 | -54,065 | -679,253 | -3,396,265 | -7,471,783 | -37,358,915 |
