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 403,146,469, 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 | 403,146,469 | |
| -1 | -403,146,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,146,469.
Example:
1 x 403,146,469 = 403,146,469
and
-1 x -403,146,469 = 403,146,469
Notice both answers equal 403,146,469
With that explanation out of the way, let's continue. Next, we take the number 403,146,469 and divide it by 2:
403,146,469 ÷ 2 = 201,573,234.5
If the quotient is a whole number, then 2 and 201,573,234.5 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 | 403,146,469 | |
| -1 | -403,146,469 |
Now, we try dividing 403,146,469 by 3:
403,146,469 ÷ 3 = 134,382,156.3333
If the quotient is a whole number, then 3 and 134,382,156.3333 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 | 403,146,469 | |
| -1 | -403,146,469 |
Let's try dividing by 4:
403,146,469 ÷ 4 = 100,786,617.25
If the quotient is a whole number, then 4 and 100,786,617.25 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 | 403,146,469 | |
| -1 | 403,146,469 |
If you did it right, you will end up with this table:
| 1 | 11 | 59 | 121 | 149 | 379 | 649 | 1,639 | 4,169 | 7,139 | 8,791 | 18,029 | 22,361 | 45,859 | 56,471 | 96,701 | 245,971 | 621,181 | 1,063,711 | 2,705,681 | 3,331,789 | 6,832,991 | 36,649,679 | 403,146,469 |
| -1 | -11 | -59 | -121 | -149 | -379 | -649 | -1,639 | -4,169 | -7,139 | -8,791 | -18,029 | -22,361 | -45,859 | -56,471 | -96,701 | -245,971 | -621,181 | -1,063,711 | -2,705,681 | -3,331,789 | -6,832,991 | -36,649,679 | -403,146,469 |
