How do I find the factor combinations of the number 705,055,505?

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 705,055,505, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

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.

1 705,055,505
-1 -705,055,505

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 705,055,505.

Example:
1 x 705,055,505 = 705,055,505
and
-1 x -705,055,505 = 705,055,505
Notice both answers equal 705,055,505

With that explanation out of the way, let's continue. Next, we take the number 705,055,505 and divide it by 2:

705,055,505 ÷ 2 = 352,527,752.5

If the quotient is a whole number, then 2 and 352,527,752.5 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:

1 705,055,505
-1 -705,055,505

Now, we try dividing 705,055,505 by 3:

705,055,505 ÷ 3 = 235,018,501.6667

If the quotient is a whole number, then 3 and 235,018,501.6667 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:

1 705,055,505
-1 -705,055,505

Let's try dividing by 4:

705,055,505 ÷ 4 = 176,263,876.25

If the quotient is a whole number, then 4 and 176,263,876.25 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:

1 705,055,505
-1 705,055,505
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:

157113555771212293856057278471,1451,6032,5193,6354,2355,0897,9978,01512,59517,63325,44527,70939,98555,97987,96788,165138,545166,483193,963279,895439,835615,769832,415969,8151,165,3811,831,3133,078,8455,826,9059,156,56512,819,19120,144,44364,095,955100,722,215141,011,101705,055,505
