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 103,142,053, 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 | 103,142,053 | |
| -1 | -103,142,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,142,053.
Example:
1 x 103,142,053 = 103,142,053
and
-1 x -103,142,053 = 103,142,053
Notice both answers equal 103,142,053
With that explanation out of the way, let's continue. Next, we take the number 103,142,053 and divide it by 2:
103,142,053 ÷ 2 = 51,571,026.5
If the quotient is a whole number, then 2 and 51,571,026.5 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 | 103,142,053 | |
| -1 | -103,142,053 |
Now, we try dividing 103,142,053 by 3:
103,142,053 ÷ 3 = 34,380,684.3333
If the quotient is a whole number, then 3 and 34,380,684.3333 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 | 103,142,053 | |
| -1 | -103,142,053 |
Let's try dividing by 4:
103,142,053 ÷ 4 = 25,785,513.25
If the quotient is a whole number, then 4 and 25,785,513.25 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 | 103,142,053 | |
| -1 | 103,142,053 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 421 | 1,129 | 2,947 | 7,903 | 13,051 | 34,999 | 91,357 | 244,993 | 475,309 | 3,327,163 | 14,734,579 | 103,142,053 |
| -1 | -7 | -31 | -217 | -421 | -1,129 | -2,947 | -7,903 | -13,051 | -34,999 | -91,357 | -244,993 | -475,309 | -3,327,163 | -14,734,579 | -103,142,053 |
