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 35,726,821, 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 | 35,726,821 | |
| -1 | -35,726,821 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,726,821.
Example:
1 x 35,726,821 = 35,726,821
and
-1 x -35,726,821 = 35,726,821
Notice both answers equal 35,726,821
With that explanation out of the way, let's continue. Next, we take the number 35,726,821 and divide it by 2:
35,726,821 ÷ 2 = 17,863,410.5
If the quotient is a whole number, then 2 and 17,863,410.5 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 | 35,726,821 | |
| -1 | -35,726,821 |
Now, we try dividing 35,726,821 by 3:
35,726,821 ÷ 3 = 11,908,940.3333
If the quotient is a whole number, then 3 and 11,908,940.3333 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 | 35,726,821 | |
| -1 | -35,726,821 |
Let's try dividing by 4:
35,726,821 ÷ 4 = 8,931,705.25
If the quotient is a whole number, then 4 and 8,931,705.25 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 | 35,726,821 | |
| -1 | 35,726,821 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 109 | 247 | 1,327 | 1,417 | 2,071 | 17,251 | 25,213 | 26,923 | 144,643 | 327,769 | 1,880,359 | 2,748,217 | 35,726,821 |
| -1 | -13 | -19 | -109 | -247 | -1,327 | -1,417 | -2,071 | -17,251 | -25,213 | -26,923 | -144,643 | -327,769 | -1,880,359 | -2,748,217 | -35,726,821 |
