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 464,381,575, 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 | 464,381,575 | |
| -1 | -464,381,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 464,381,575.
Example:
1 x 464,381,575 = 464,381,575
and
-1 x -464,381,575 = 464,381,575
Notice both answers equal 464,381,575
With that explanation out of the way, let's continue. Next, we take the number 464,381,575 and divide it by 2:
464,381,575 ÷ 2 = 232,190,787.5
If the quotient is a whole number, then 2 and 232,190,787.5 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 | 464,381,575 | |
| -1 | -464,381,575 |
Now, we try dividing 464,381,575 by 3:
464,381,575 ÷ 3 = 154,793,858.3333
If the quotient is a whole number, then 3 and 154,793,858.3333 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 | 464,381,575 | |
| -1 | -464,381,575 |
Let's try dividing by 4:
464,381,575 ÷ 4 = 116,095,393.75
If the quotient is a whole number, then 4 and 116,095,393.75 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 | 464,381,575 | |
| -1 | 464,381,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 379,087 | 1,895,435 | 2,653,609 | 9,477,175 | 13,268,045 | 18,575,263 | 66,340,225 | 92,876,315 | 464,381,575 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -379,087 | -1,895,435 | -2,653,609 | -9,477,175 | -13,268,045 | -18,575,263 | -66,340,225 | -92,876,315 | -464,381,575 |
