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 107,037,161, 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 | 107,037,161 | |
| -1 | -107,037,161 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 107,037,161.
Example:
1 x 107,037,161 = 107,037,161
and
-1 x -107,037,161 = 107,037,161
Notice both answers equal 107,037,161
With that explanation out of the way, let's continue. Next, we take the number 107,037,161 and divide it by 2:
107,037,161 ÷ 2 = 53,518,580.5
If the quotient is a whole number, then 2 and 53,518,580.5 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 | 107,037,161 | |
| -1 | -107,037,161 |
Now, we try dividing 107,037,161 by 3:
107,037,161 ÷ 3 = 35,679,053.6667
If the quotient is a whole number, then 3 and 35,679,053.6667 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 | 107,037,161 | |
| -1 | -107,037,161 |
Let's try dividing by 4:
107,037,161 ÷ 4 = 26,759,290.25
If the quotient is a whole number, then 4 and 26,759,290.25 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 | 107,037,161 | |
| -1 | 107,037,161 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 631 | 2,203 | 4,417 | 6,941 | 15,421 | 24,233 | 48,587 | 169,631 | 1,390,093 | 9,730,651 | 15,291,023 | 107,037,161 |
| -1 | -7 | -11 | -77 | -631 | -2,203 | -4,417 | -6,941 | -15,421 | -24,233 | -48,587 | -169,631 | -1,390,093 | -9,730,651 | -15,291,023 | -107,037,161 |
