Start with the prime factorization.
In Exponential Form: 2^2 x 3^1 x 4517^1
Adding one to the exponents and multiplying gives you the number of factors.
3 x 2 x 2 = 12
54204 has twelve factors. All we need to find is 6. Dividing them into 54204 will give us the other 6.
Apply what you know about the rules of divisibility.
1 is because 1 always is.
2 is because it's even.
3 is because the digits add up to a multiple of 3.
4 is because the last two digits are a multiple of 4.
6 is because 2 and 3 are.
That leaves one to find. We know 4517 is a factor from the prime factorization. Dividing that into 54204 gives us 12. That's all of them.
All Factors of 54204: 1, 2, 3, 4, 6, 12, 4517, 9034, 13551, 18068, 27102, 54204

You could. All of the factors of 100 are factors of 200.
Factors refer to whole numbers, not decimals.
Once all the prime factors of a number have been found, the number of factors the number has and what they are can be found. I'd be finding the prime factors first before finding all the factors of a number, so I'd rather find all the prime factors as it means I can stop before I have to do more work in finding all the factors.
