The easiest way is through easy websites such as this: http://wiki.answers.com/Q/What_are_the_factors_of_math
Alternatively, you can use prime factorization. In this case, 1800 = 2*2*2*3*3*5*5. Thus any divisor contains at most three factors of 2;
that means there are four possibilities: 0, 1, 2, or 3 factors of 2. Similarly there are three possibilities for the number of factors of 3 in a divisor, and the same for factors of 5. Multiplying these together, we find there are 4*3*3 = 36 positive integer divisors of 1800.
In general, take the exponents in the prime factorization, add one to each of them, and multiply the resulting numbers together.

Odd. I determined my answer by looking at the number of factors of a square number.
Is 15 a factor of 240 Give reason?
To calculate factors using this tool, you will enter positive integers, because the calculator will only allow positive values, to calculate factors of a number. if you need to calculate negative numbers, you enter the positive value, get the factors and duplicate the answer yourself with all the give positive factors as negatives like as -5 and -6 as factors of number 30.
How do you determine if a number is a composite number?
A composite number is a positive integer with more than two factors.
Does the number of positive factors affect the sign of the product?
No. Any number of positive factors will lead to a positive product.
How many positive factors does the number 175 have?
The number 175 is an odd number. This number, 175 has four positive factors (35,5 and 25,7). These number are all positive and when multiplies equal 175.
How can you tell from the number of factors when a product is positive or negative?
If you are multiplying negative numbers, an odd number of factors will have a negative product. An even number of factors will have a positive product.
What are positive integral factors?
they are simply the factors of a number
How do you determine what is a prime number?
A prime number is a positive integer with two factors: one and the number itself. If you test the numbers up to the square root and your number is not divisible by any of them, it's prime.
How do you determine if prime number?
A prime number is a positive integer with two factors: one and the number itself. If you test the numbers up to the square root and your number is not divisible by any of them, it's prime.
What are the positive factors for 41?
41 is a prime number. So the positive factors are 1 & 41

How do you determine whether a no is prime or not?
A prime number is a positive integer with two factors: one and the number itself. If you test the numbers up to the square root and your number is not divisible by any of them, it's prime.
What are the numbers that are not prime or composite?
A prime number is a number with two positive integer factors, while a composite number has more than two positive integer factors. Since the number 0 has no positive integer factors, and the number 1 has just one positive integer factor (itself), neither of these are prime.
