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 75,037,165, 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 | 75,037,165 | |
| -1 | -75,037,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,037,165.
Example:
1 x 75,037,165 = 75,037,165
and
-1 x -75,037,165 = 75,037,165
Notice both answers equal 75,037,165
With that explanation out of the way, let's continue. Next, we take the number 75,037,165 and divide it by 2:
75,037,165 ÷ 2 = 37,518,582.5
If the quotient is a whole number, then 2 and 37,518,582.5 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 | 75,037,165 | |
| -1 | -75,037,165 |
Now, we try dividing 75,037,165 by 3:
75,037,165 ÷ 3 = 25,012,388.3333
If the quotient is a whole number, then 3 and 25,012,388.3333 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 | 75,037,165 | |
| -1 | -75,037,165 |
Let's try dividing by 4:
75,037,165 ÷ 4 = 18,759,291.25
If the quotient is a whole number, then 4 and 18,759,291.25 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 | 75,037,165 | |
| -1 | 75,037,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,223 | 1,753 | 6,115 | 8,561 | 8,765 | 12,271 | 42,805 | 61,355 | 2,143,919 | 10,719,595 | 15,007,433 | 75,037,165 |
| -1 | -5 | -7 | -35 | -1,223 | -1,753 | -6,115 | -8,561 | -8,765 | -12,271 | -42,805 | -61,355 | -2,143,919 | -10,719,595 | -15,007,433 | -75,037,165 |
