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 147,410,767, 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 | 147,410,767 | |
| -1 | -147,410,767 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,410,767.
Example:
1 x 147,410,767 = 147,410,767
and
-1 x -147,410,767 = 147,410,767
Notice both answers equal 147,410,767
With that explanation out of the way, let's continue. Next, we take the number 147,410,767 and divide it by 2:
147,410,767 ÷ 2 = 73,705,383.5
If the quotient is a whole number, then 2 and 73,705,383.5 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 | 147,410,767 | |
| -1 | -147,410,767 |
Now, we try dividing 147,410,767 by 3:
147,410,767 ÷ 3 = 49,136,922.3333
If the quotient is a whole number, then 3 and 49,136,922.3333 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 | 147,410,767 | |
| -1 | -147,410,767 |
Let's try dividing by 4:
147,410,767 ÷ 4 = 36,852,691.75
If the quotient is a whole number, then 4 and 36,852,691.75 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 | 147,410,767 | |
| -1 | 147,410,767 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 137 | 343 | 959 | 3,137 | 6,713 | 21,959 | 46,991 | 153,713 | 429,769 | 1,075,991 | 3,008,383 | 21,058,681 | 147,410,767 |
| -1 | -7 | -49 | -137 | -343 | -959 | -3,137 | -6,713 | -21,959 | -46,991 | -153,713 | -429,769 | -1,075,991 | -3,008,383 | -21,058,681 | -147,410,767 |
