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 356,130,551, 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 | 356,130,551 | |
| -1 | -356,130,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,130,551.
Example:
1 x 356,130,551 = 356,130,551
and
-1 x -356,130,551 = 356,130,551
Notice both answers equal 356,130,551
With that explanation out of the way, let's continue. Next, we take the number 356,130,551 and divide it by 2:
356,130,551 ÷ 2 = 178,065,275.5
If the quotient is a whole number, then 2 and 178,065,275.5 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 | 356,130,551 | |
| -1 | -356,130,551 |
Now, we try dividing 356,130,551 by 3:
356,130,551 ÷ 3 = 118,710,183.6667
If the quotient is a whole number, then 3 and 118,710,183.6667 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 | 356,130,551 | |
| -1 | -356,130,551 |
Let's try dividing by 4:
356,130,551 ÷ 4 = 89,032,637.75
If the quotient is a whole number, then 4 and 89,032,637.75 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 | 356,130,551 | |
| -1 | 356,130,551 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 41 | 161 | 287 | 943 | 6,601 | 53,951 | 377,657 | 1,240,873 | 2,211,991 | 8,686,111 | 15,483,937 | 50,875,793 | 356,130,551 |
| -1 | -7 | -23 | -41 | -161 | -287 | -943 | -6,601 | -53,951 | -377,657 | -1,240,873 | -2,211,991 | -8,686,111 | -15,483,937 | -50,875,793 | -356,130,551 |
