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 factors of larger numbers. To find the factors of the number 210,026,420, it is easiest to start from the outside in. Here's what we mean:
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.
| 1 | 210,026,420 |
Next, we take the number 210,026,420 and divide it by 2.
In this case, 210,026,420 ÷ 2 = 105,013,210
If the quotient is a whole number, then 2 and 105,013,210 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.
| 1 | 2 | 105,013,210 | 210,026,420 |
Now, we try dividing 210,026,420 by 3.
210,026,420 ÷ 3 = 70,008,806.6667
If the quotient is a whole number, then 3 and 70,008,806.6667 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.
Here is what our table should look like at this step:
| 1 | 2 | 105,013,210 | 210,026,420 |
Let's try dividing by 4.
210,026,420 ÷ 4 = 52,506,605
If the quotient is a whole number, then 4 and 52,506,605 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.
Here is what our table should look like at this step:
| 1 | 2 | 4 | 52,506,605 | 105,013,210 | 210,026,420 |
We keep dividing by the next largest number, in this case the number 5. If the quotient of 210,026,420 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.
Keep dividing by the next highest number until you cannot divide anymore.
What you will end up with is this table:
| 1 | 2 | 4 | 5 | 10 | 20 | 10,501,321 | 21,002,642 | 42,005,284 | 52,506,605 | 105,013,210 | 210,026,420 |
All of the numbers in the table above can be evenly divided into the number 210,026,420.
Finally, for your reference, here are all of the divisor combinations of the number 210,026,420:
1 x 210026420
2 x 105013210
4 x 52506605
5 x 42005284
10 x 21002642
20 x 10501321
