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 464,353,771, 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 | 464,353,771 | |
| -1 | -464,353,771 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 464,353,771.
Example:
1 x 464,353,771 = 464,353,771
and
-1 x -464,353,771 = 464,353,771
Notice both answers equal 464,353,771
With that explanation out of the way, let's continue. Next, we take the number 464,353,771 and divide it by 2:
464,353,771 ÷ 2 = 232,176,885.5
If the quotient is a whole number, then 2 and 232,176,885.5 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 | 464,353,771 | |
| -1 | -464,353,771 |
Now, we try dividing 464,353,771 by 3:
464,353,771 ÷ 3 = 154,784,590.3333
If the quotient is a whole number, then 3 and 154,784,590.3333 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 | 464,353,771 | |
| -1 | -464,353,771 |
Let's try dividing by 4:
464,353,771 ÷ 4 = 116,088,442.75
If the quotient is a whole number, then 4 and 116,088,442.75 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 | 464,353,771 | |
| -1 | 464,353,771 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 307 | 2,149 | 7,451 | 8,903 | 52,157 | 62,321 | 216,079 | 1,512,553 | 2,287,457 | 16,012,199 | 66,336,253 | 464,353,771 |
| -1 | -7 | -29 | -203 | -307 | -2,149 | -7,451 | -8,903 | -52,157 | -62,321 | -216,079 | -1,512,553 | -2,287,457 | -16,012,199 | -66,336,253 | -464,353,771 |
