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 35,374,685, 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 | 35,374,685 | |
| -1 | -35,374,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,374,685.
Example:
1 x 35,374,685 = 35,374,685
and
-1 x -35,374,685 = 35,374,685
Notice both answers equal 35,374,685
With that explanation out of the way, let's continue. Next, we take the number 35,374,685 and divide it by 2:
35,374,685 ÷ 2 = 17,687,342.5
If the quotient is a whole number, then 2 and 17,687,342.5 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 | 35,374,685 | |
| -1 | -35,374,685 |
Now, we try dividing 35,374,685 by 3:
35,374,685 ÷ 3 = 11,791,561.6667
If the quotient is a whole number, then 3 and 11,791,561.6667 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 | 35,374,685 | |
| -1 | -35,374,685 |
Let's try dividing by 4:
35,374,685 ÷ 4 = 8,843,671.25
If the quotient is a whole number, then 4 and 8,843,671.25 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 | 35,374,685 | |
| -1 | 35,374,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 251 | 355 | 397 | 1,255 | 1,985 | 17,821 | 28,187 | 89,105 | 99,647 | 140,935 | 498,235 | 7,074,937 | 35,374,685 |
| -1 | -5 | -71 | -251 | -355 | -397 | -1,255 | -1,985 | -17,821 | -28,187 | -89,105 | -99,647 | -140,935 | -498,235 | -7,074,937 | -35,374,685 |
