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 141,772,267, 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 | 141,772,267 | |
| -1 | -141,772,267 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,772,267.
Example:
1 x 141,772,267 = 141,772,267
and
-1 x -141,772,267 = 141,772,267
Notice both answers equal 141,772,267
With that explanation out of the way, let's continue. Next, we take the number 141,772,267 and divide it by 2:
141,772,267 ÷ 2 = 70,886,133.5
If the quotient is a whole number, then 2 and 70,886,133.5 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 | 141,772,267 | |
| -1 | -141,772,267 |
Now, we try dividing 141,772,267 by 3:
141,772,267 ÷ 3 = 47,257,422.3333
If the quotient is a whole number, then 3 and 47,257,422.3333 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 | 141,772,267 | |
| -1 | -141,772,267 |
Let's try dividing by 4:
141,772,267 ÷ 4 = 35,443,066.75
If the quotient is a whole number, then 4 and 35,443,066.75 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 | 141,772,267 | |
| -1 | 141,772,267 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 109 | 763 | 1,417 | 9,919 | 14,293 | 100,051 | 185,809 | 1,300,663 | 1,557,937 | 10,905,559 | 20,253,181 | 141,772,267 |
| -1 | -7 | -13 | -91 | -109 | -763 | -1,417 | -9,919 | -14,293 | -100,051 | -185,809 | -1,300,663 | -1,557,937 | -10,905,559 | -20,253,181 | -141,772,267 |
