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 654,056,045, 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 | 654,056,045 | |
| -1 | -654,056,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 654,056,045.
Example:
1 x 654,056,045 = 654,056,045
and
-1 x -654,056,045 = 654,056,045
Notice both answers equal 654,056,045
With that explanation out of the way, let's continue. Next, we take the number 654,056,045 and divide it by 2:
654,056,045 ÷ 2 = 327,028,022.5
If the quotient is a whole number, then 2 and 327,028,022.5 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 | 654,056,045 | |
| -1 | -654,056,045 |
Now, we try dividing 654,056,045 by 3:
654,056,045 ÷ 3 = 218,018,681.6667
If the quotient is a whole number, then 3 and 218,018,681.6667 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 | 654,056,045 | |
| -1 | -654,056,045 |
Let's try dividing by 4:
654,056,045 ÷ 4 = 163,514,011.25
If the quotient is a whole number, then 4 and 163,514,011.25 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 | 654,056,045 | |
| -1 | 654,056,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 709 | 3,545 | 10,853 | 12,053 | 54,265 | 60,265 | 184,501 | 922,505 | 7,694,777 | 38,473,885 | 130,811,209 | 654,056,045 |
| -1 | -5 | -17 | -85 | -709 | -3,545 | -10,853 | -12,053 | -54,265 | -60,265 | -184,501 | -922,505 | -7,694,777 | -38,473,885 | -130,811,209 | -654,056,045 |
