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 464,152,645, 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 | 464,152,645 | |
| -1 | -464,152,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 464,152,645.
Example:
1 x 464,152,645 = 464,152,645
and
-1 x -464,152,645 = 464,152,645
Notice both answers equal 464,152,645
With that explanation out of the way, let's continue. Next, we take the number 464,152,645 and divide it by 2:
464,152,645 ÷ 2 = 232,076,322.5
If the quotient is a whole number, then 2 and 232,076,322.5 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 | 464,152,645 | |
| -1 | -464,152,645 |
Now, we try dividing 464,152,645 by 3:
464,152,645 ÷ 3 = 154,717,548.3333
If the quotient is a whole number, then 3 and 154,717,548.3333 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 | 464,152,645 | |
| -1 | -464,152,645 |
Let's try dividing by 4:
464,152,645 ÷ 4 = 116,038,161.25
If the quotient is a whole number, then 4 and 116,038,161.25 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 | 464,152,645 | |
| -1 | 464,152,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 2,477 | 3,407 | 12,385 | 17,035 | 27,247 | 37,477 | 136,235 | 187,385 | 8,439,139 | 42,195,695 | 92,830,529 | 464,152,645 |
| -1 | -5 | -11 | -55 | -2,477 | -3,407 | -12,385 | -17,035 | -27,247 | -37,477 | -136,235 | -187,385 | -8,439,139 | -42,195,695 | -92,830,529 | -464,152,645 |
