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 610,777,363, 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 | 610,777,363 | |
| -1 | -610,777,363 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 610,777,363.
Example:
1 x 610,777,363 = 610,777,363
and
-1 x -610,777,363 = 610,777,363
Notice both answers equal 610,777,363
With that explanation out of the way, let's continue. Next, we take the number 610,777,363 and divide it by 2:
610,777,363 ÷ 2 = 305,388,681.5
If the quotient is a whole number, then 2 and 305,388,681.5 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 | 610,777,363 | |
| -1 | -610,777,363 |
Now, we try dividing 610,777,363 by 3:
610,777,363 ÷ 3 = 203,592,454.3333
If the quotient is a whole number, then 3 and 203,592,454.3333 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 | 610,777,363 | |
| -1 | -610,777,363 |
Let's try dividing by 4:
610,777,363 ÷ 4 = 152,694,340.75
If the quotient is a whole number, then 4 and 152,694,340.75 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 | 610,777,363 | |
| -1 | 610,777,363 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 89 | 133 | 623 | 1,691 | 11,837 | 51,599 | 361,193 | 980,381 | 4,592,311 | 6,862,667 | 32,146,177 | 87,253,909 | 610,777,363 |
| -1 | -7 | -19 | -89 | -133 | -623 | -1,691 | -11,837 | -51,599 | -361,193 | -980,381 | -4,592,311 | -6,862,667 | -32,146,177 | -87,253,909 | -610,777,363 |
