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 63,569,191, 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 | 63,569,191 | |
| -1 | -63,569,191 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,569,191.
Example:
1 x 63,569,191 = 63,569,191
and
-1 x -63,569,191 = 63,569,191
Notice both answers equal 63,569,191
With that explanation out of the way, let's continue. Next, we take the number 63,569,191 and divide it by 2:
63,569,191 ÷ 2 = 31,784,595.5
If the quotient is a whole number, then 2 and 31,784,595.5 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 | 63,569,191 | |
| -1 | -63,569,191 |
Now, we try dividing 63,569,191 by 3:
63,569,191 ÷ 3 = 21,189,730.3333
If the quotient is a whole number, then 3 and 21,189,730.3333 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 | 63,569,191 | |
| -1 | -63,569,191 |
Let's try dividing by 4:
63,569,191 ÷ 4 = 15,892,297.75
If the quotient is a whole number, then 4 and 15,892,297.75 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 | 63,569,191 | |
| -1 | 63,569,191 |
If you did it right, you will end up with this table:
| 1 | 7 | 131 | 181 | 383 | 917 | 1,267 | 2,681 | 23,711 | 50,173 | 69,323 | 165,977 | 351,211 | 485,261 | 9,081,313 | 63,569,191 |
| -1 | -7 | -131 | -181 | -383 | -917 | -1,267 | -2,681 | -23,711 | -50,173 | -69,323 | -165,977 | -351,211 | -485,261 | -9,081,313 | -63,569,191 |
