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 404,152,363, 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 | 404,152,363 | |
| -1 | -404,152,363 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,152,363.
Example:
1 x 404,152,363 = 404,152,363
and
-1 x -404,152,363 = 404,152,363
Notice both answers equal 404,152,363
With that explanation out of the way, let's continue. Next, we take the number 404,152,363 and divide it by 2:
404,152,363 ÷ 2 = 202,076,181.5
If the quotient is a whole number, then 2 and 202,076,181.5 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 | 404,152,363 | |
| -1 | -404,152,363 |
Now, we try dividing 404,152,363 by 3:
404,152,363 ÷ 3 = 134,717,454.3333
If the quotient is a whole number, then 3 and 134,717,454.3333 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 | 404,152,363 | |
| -1 | -404,152,363 |
Let's try dividing by 4:
404,152,363 ÷ 4 = 101,038,090.75
If the quotient is a whole number, then 4 and 101,038,090.75 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 | 404,152,363 | |
| -1 | 404,152,363 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 263 | 589 | 2,609 | 4,997 | 8,153 | 49,571 | 80,879 | 154,907 | 686,167 | 1,536,701 | 13,037,173 | 21,271,177 | 404,152,363 |
| -1 | -19 | -31 | -263 | -589 | -2,609 | -4,997 | -8,153 | -49,571 | -80,879 | -154,907 | -686,167 | -1,536,701 | -13,037,173 | -21,271,177 | -404,152,363 |
