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 51,895,655, 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 | 51,895,655 | |
| -1 | -51,895,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,895,655.
Example:
1 x 51,895,655 = 51,895,655
and
-1 x -51,895,655 = 51,895,655
Notice both answers equal 51,895,655
With that explanation out of the way, let's continue. Next, we take the number 51,895,655 and divide it by 2:
51,895,655 ÷ 2 = 25,947,827.5
If the quotient is a whole number, then 2 and 25,947,827.5 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 | 51,895,655 | |
| -1 | -51,895,655 |
Now, we try dividing 51,895,655 by 3:
51,895,655 ÷ 3 = 17,298,551.6667
If the quotient is a whole number, then 3 and 17,298,551.6667 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 | 51,895,655 | |
| -1 | -51,895,655 |
Let's try dividing by 4:
51,895,655 ÷ 4 = 12,973,913.75
If the quotient is a whole number, then 4 and 12,973,913.75 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 | 51,895,655 | |
| -1 | 51,895,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 191 | 245 | 955 | 1,109 | 1,337 | 5,545 | 6,685 | 7,763 | 9,359 | 38,815 | 46,795 | 54,341 | 211,819 | 271,705 | 1,059,095 | 1,482,733 | 7,413,665 | 10,379,131 | 51,895,655 |
| -1 | -5 | -7 | -35 | -49 | -191 | -245 | -955 | -1,109 | -1,337 | -5,545 | -6,685 | -7,763 | -9,359 | -38,815 | -46,795 | -54,341 | -211,819 | -271,705 | -1,059,095 | -1,482,733 | -7,413,665 | -10,379,131 | -51,895,655 |
