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 103,610,743, 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 | 103,610,743 | |
| -1 | -103,610,743 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,610,743.
Example:
1 x 103,610,743 = 103,610,743
and
-1 x -103,610,743 = 103,610,743
Notice both answers equal 103,610,743
With that explanation out of the way, let's continue. Next, we take the number 103,610,743 and divide it by 2:
103,610,743 ÷ 2 = 51,805,371.5
If the quotient is a whole number, then 2 and 51,805,371.5 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 | 103,610,743 | |
| -1 | -103,610,743 |
Now, we try dividing 103,610,743 by 3:
103,610,743 ÷ 3 = 34,536,914.3333
If the quotient is a whole number, then 3 and 34,536,914.3333 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 | 103,610,743 | |
| -1 | -103,610,743 |
Let's try dividing by 4:
103,610,743 ÷ 4 = 25,902,685.75
If the quotient is a whole number, then 4 and 25,902,685.75 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 | 103,610,743 | |
| -1 | 103,610,743 |
If you did it right, you will end up with this table:
| 1 | 19 | 67 | 199 | 409 | 1,273 | 3,781 | 7,771 | 13,333 | 27,403 | 81,391 | 253,327 | 520,657 | 1,546,429 | 5,453,197 | 103,610,743 |
| -1 | -19 | -67 | -199 | -409 | -1,273 | -3,781 | -7,771 | -13,333 | -27,403 | -81,391 | -253,327 | -520,657 | -1,546,429 | -5,453,197 | -103,610,743 |
