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 51,500,089, 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 | 51,500,089 | |
| -1 | -51,500,089 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,500,089.
Example:
1 x 51,500,089 = 51,500,089
and
-1 x -51,500,089 = 51,500,089
Notice both answers equal 51,500,089
With that explanation out of the way, let's continue. Next, we take the number 51,500,089 and divide it by 2:
51,500,089 ÷ 2 = 25,750,044.5
If the quotient is a whole number, then 2 and 25,750,044.5 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 | 51,500,089 | |
| -1 | -51,500,089 |
Now, we try dividing 51,500,089 by 3:
51,500,089 ÷ 3 = 17,166,696.3333
If the quotient is a whole number, then 3 and 17,166,696.3333 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 | 51,500,089 | |
| -1 | -51,500,089 |
Let's try dividing by 4:
51,500,089 ÷ 4 = 12,875,022.25
If the quotient is a whole number, then 4 and 12,875,022.25 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 | 51,500,089 | |
| -1 | 51,500,089 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 83 | 113 | 289 | 323 | 1,411 | 1,577 | 1,921 | 2,147 | 5,491 | 9,379 | 23,987 | 26,809 | 32,657 | 36,499 | 159,443 | 178,201 | 455,753 | 620,483 | 2,710,531 | 3,029,417 | 51,500,089 |
| -1 | -17 | -19 | -83 | -113 | -289 | -323 | -1,411 | -1,577 | -1,921 | -2,147 | -5,491 | -9,379 | -23,987 | -26,809 | -32,657 | -36,499 | -159,443 | -178,201 | -455,753 | -620,483 | -2,710,531 | -3,029,417 | -51,500,089 |
