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 3,545,971, 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 | 3,545,971 | |
| -1 | -3,545,971 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,545,971.
Example:
1 x 3,545,971 = 3,545,971
and
-1 x -3,545,971 = 3,545,971
Notice both answers equal 3,545,971
With that explanation out of the way, let's continue. Next, we take the number 3,545,971 and divide it by 2:
3,545,971 ÷ 2 = 1,772,985.5
If the quotient is a whole number, then 2 and 1,772,985.5 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 | 3,545,971 | |
| -1 | -3,545,971 |
Now, we try dividing 3,545,971 by 3:
3,545,971 ÷ 3 = 1,181,990.3333
If the quotient is a whole number, then 3 and 1,181,990.3333 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 | 3,545,971 | |
| -1 | -3,545,971 |
Let's try dividing by 4:
3,545,971 ÷ 4 = 886,492.75
If the quotient is a whole number, then 4 and 886,492.75 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 | 3,545,971 | |
| -1 | 3,545,971 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 137 | 143 | 181 | 1,507 | 1,781 | 1,991 | 2,353 | 19,591 | 24,797 | 25,883 | 272,767 | 322,361 | 3,545,971 |
| -1 | -11 | -13 | -137 | -143 | -181 | -1,507 | -1,781 | -1,991 | -2,353 | -19,591 | -24,797 | -25,883 | -272,767 | -322,361 | -3,545,971 |
