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 147,620,363, 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 | 147,620,363 | |
| -1 | -147,620,363 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,620,363.
Example:
1 x 147,620,363 = 147,620,363
and
-1 x -147,620,363 = 147,620,363
Notice both answers equal 147,620,363
With that explanation out of the way, let's continue. Next, we take the number 147,620,363 and divide it by 2:
147,620,363 ÷ 2 = 73,810,181.5
If the quotient is a whole number, then 2 and 73,810,181.5 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 | 147,620,363 | |
| -1 | -147,620,363 |
Now, we try dividing 147,620,363 by 3:
147,620,363 ÷ 3 = 49,206,787.6667
If the quotient is a whole number, then 3 and 49,206,787.6667 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 | 147,620,363 | |
| -1 | -147,620,363 |
Let's try dividing by 4:
147,620,363 ÷ 4 = 36,905,090.75
If the quotient is a whole number, then 4 and 36,905,090.75 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 | 147,620,363 | |
| -1 | 147,620,363 |
If you did it right, you will end up with this table:
| 1 | 11 | 67 | 121 | 131 | 139 | 737 | 1,441 | 1,529 | 8,107 | 8,777 | 9,313 | 15,851 | 16,819 | 18,209 | 96,547 | 102,443 | 200,299 | 1,062,017 | 1,126,873 | 1,220,003 | 2,203,289 | 13,420,033 | 147,620,363 |
| -1 | -11 | -67 | -121 | -131 | -139 | -737 | -1,441 | -1,529 | -8,107 | -8,777 | -9,313 | -15,851 | -16,819 | -18,209 | -96,547 | -102,443 | -200,299 | -1,062,017 | -1,126,873 | -1,220,003 | -2,203,289 | -13,420,033 | -147,620,363 |
