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 147,726,377, 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 | 147,726,377 | |
| -1 | -147,726,377 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,726,377.
Example:
1 x 147,726,377 = 147,726,377
and
-1 x -147,726,377 = 147,726,377
Notice both answers equal 147,726,377
With that explanation out of the way, let's continue. Next, we take the number 147,726,377 and divide it by 2:
147,726,377 ÷ 2 = 73,863,188.5
If the quotient is a whole number, then 2 and 73,863,188.5 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 | 147,726,377 | |
| -1 | -147,726,377 |
Now, we try dividing 147,726,377 by 3:
147,726,377 ÷ 3 = 49,242,125.6667
If the quotient is a whole number, then 3 and 49,242,125.6667 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 | 147,726,377 | |
| -1 | -147,726,377 |
Let's try dividing by 4:
147,726,377 ÷ 4 = 36,931,594.25
If the quotient is a whole number, then 4 and 36,931,594.25 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 | 147,726,377 | |
| -1 | 147,726,377 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 73 | 899 | 2,117 | 2,251 | 2,263 | 65,279 | 65,627 | 69,781 | 164,323 | 2,023,649 | 4,765,367 | 5,094,013 | 147,726,377 |
| -1 | -29 | -31 | -73 | -899 | -2,117 | -2,251 | -2,263 | -65,279 | -65,627 | -69,781 | -164,323 | -2,023,649 | -4,765,367 | -5,094,013 | -147,726,377 |
