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 610,173,155, 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 | 610,173,155 | |
| -1 | -610,173,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 610,173,155.
Example:
1 x 610,173,155 = 610,173,155
and
-1 x -610,173,155 = 610,173,155
Notice both answers equal 610,173,155
With that explanation out of the way, let's continue. Next, we take the number 610,173,155 and divide it by 2:
610,173,155 ÷ 2 = 305,086,577.5
If the quotient is a whole number, then 2 and 305,086,577.5 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 | 610,173,155 | |
| -1 | -610,173,155 |
Now, we try dividing 610,173,155 by 3:
610,173,155 ÷ 3 = 203,391,051.6667
If the quotient is a whole number, then 3 and 203,391,051.6667 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 | 610,173,155 | |
| -1 | -610,173,155 |
Let's try dividing by 4:
610,173,155 ÷ 4 = 152,543,288.75
If the quotient is a whole number, then 4 and 152,543,288.75 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 | 610,173,155 | |
| -1 | 610,173,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 313 | 1,565 | 9,703 | 12,577 | 48,515 | 62,885 | 389,887 | 1,949,435 | 3,936,601 | 19,683,005 | 122,034,631 | 610,173,155 |
| -1 | -5 | -31 | -155 | -313 | -1,565 | -9,703 | -12,577 | -48,515 | -62,885 | -389,887 | -1,949,435 | -3,936,601 | -19,683,005 | -122,034,631 | -610,173,155 |
