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 153,567,547, 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 | 153,567,547 | |
| -1 | -153,567,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,567,547.
Example:
1 x 153,567,547 = 153,567,547
and
-1 x -153,567,547 = 153,567,547
Notice both answers equal 153,567,547
With that explanation out of the way, let's continue. Next, we take the number 153,567,547 and divide it by 2:
153,567,547 ÷ 2 = 76,783,773.5
If the quotient is a whole number, then 2 and 76,783,773.5 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 | 153,567,547 | |
| -1 | -153,567,547 |
Now, we try dividing 153,567,547 by 3:
153,567,547 ÷ 3 = 51,189,182.3333
If the quotient is a whole number, then 3 and 51,189,182.3333 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 | 153,567,547 | |
| -1 | -153,567,547 |
Let's try dividing by 4:
153,567,547 ÷ 4 = 38,391,886.75
If the quotient is a whole number, then 4 and 38,391,886.75 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 | 153,567,547 | |
| -1 | 153,567,547 |
If you did it right, you will end up with this table:
| 1 | 7 | 79 | 137 | 553 | 959 | 2,027 | 10,823 | 14,189 | 75,761 | 160,133 | 277,699 | 1,120,931 | 1,943,893 | 21,938,221 | 153,567,547 |
| -1 | -7 | -79 | -137 | -553 | -959 | -2,027 | -10,823 | -14,189 | -75,761 | -160,133 | -277,699 | -1,120,931 | -1,943,893 | -21,938,221 | -153,567,547 |
