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 54,142,207, 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 | 54,142,207 | |
| -1 | -54,142,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,142,207.
Example:
1 x 54,142,207 = 54,142,207
and
-1 x -54,142,207 = 54,142,207
Notice both answers equal 54,142,207
With that explanation out of the way, let's continue. Next, we take the number 54,142,207 and divide it by 2:
54,142,207 ÷ 2 = 27,071,103.5
If the quotient is a whole number, then 2 and 27,071,103.5 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 | 54,142,207 | |
| -1 | -54,142,207 |
Now, we try dividing 54,142,207 by 3:
54,142,207 ÷ 3 = 18,047,402.3333
If the quotient is a whole number, then 3 and 18,047,402.3333 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 | 54,142,207 | |
| -1 | -54,142,207 |
Let's try dividing by 4:
54,142,207 ÷ 4 = 13,535,551.75
If the quotient is a whole number, then 4 and 13,535,551.75 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 | 54,142,207 | |
| -1 | 54,142,207 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 49 | 161 | 343 | 1,127 | 6,863 | 7,889 | 48,041 | 157,849 | 336,287 | 1,104,943 | 2,354,009 | 7,734,601 | 54,142,207 |
| -1 | -7 | -23 | -49 | -161 | -343 | -1,127 | -6,863 | -7,889 | -48,041 | -157,849 | -336,287 | -1,104,943 | -2,354,009 | -7,734,601 | -54,142,207 |
