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 406,436,611, 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 | 406,436,611 | |
| -1 | -406,436,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 406,436,611.
Example:
1 x 406,436,611 = 406,436,611
and
-1 x -406,436,611 = 406,436,611
Notice both answers equal 406,436,611
With that explanation out of the way, let's continue. Next, we take the number 406,436,611 and divide it by 2:
406,436,611 ÷ 2 = 203,218,305.5
If the quotient is a whole number, then 2 and 203,218,305.5 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 | 406,436,611 | |
| -1 | -406,436,611 |
Now, we try dividing 406,436,611 by 3:
406,436,611 ÷ 3 = 135,478,870.3333
If the quotient is a whole number, then 3 and 135,478,870.3333 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 | 406,436,611 | |
| -1 | -406,436,611 |
Let's try dividing by 4:
406,436,611 ÷ 4 = 101,609,152.75
If the quotient is a whole number, then 4 and 101,609,152.75 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 | 406,436,611 | |
| -1 | 406,436,611 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 107 | 161 | 749 | 2,461 | 17,227 | 23,593 | 165,151 | 542,639 | 2,524,451 | 3,798,473 | 17,671,157 | 58,062,373 | 406,436,611 |
| -1 | -7 | -23 | -107 | -161 | -749 | -2,461 | -17,227 | -23,593 | -165,151 | -542,639 | -2,524,451 | -3,798,473 | -17,671,157 | -58,062,373 | -406,436,611 |
