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 402,264,445, 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 | 402,264,445 | |
| -1 | -402,264,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 402,264,445.
Example:
1 x 402,264,445 = 402,264,445
and
-1 x -402,264,445 = 402,264,445
Notice both answers equal 402,264,445
With that explanation out of the way, let's continue. Next, we take the number 402,264,445 and divide it by 2:
402,264,445 ÷ 2 = 201,132,222.5
If the quotient is a whole number, then 2 and 201,132,222.5 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 | 402,264,445 | |
| -1 | -402,264,445 |
Now, we try dividing 402,264,445 by 3:
402,264,445 ÷ 3 = 134,088,148.3333
If the quotient is a whole number, then 3 and 134,088,148.3333 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 | 402,264,445 | |
| -1 | -402,264,445 |
Let's try dividing by 4:
402,264,445 ÷ 4 = 100,566,111.25
If the quotient is a whole number, then 4 and 100,566,111.25 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 | 402,264,445 | |
| -1 | 402,264,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 79 | 395 | 869 | 4,345 | 92,581 | 462,905 | 1,018,391 | 5,091,955 | 7,313,899 | 36,569,495 | 80,452,889 | 402,264,445 |
| -1 | -5 | -11 | -55 | -79 | -395 | -869 | -4,345 | -92,581 | -462,905 | -1,018,391 | -5,091,955 | -7,313,899 | -36,569,495 | -80,452,889 | -402,264,445 |
