What numbers would you divide 899 by to determine if its prime or to prime factor it?

29 and 31


When getting a prime factor do you divide or multiply?

To get a prime factor, you would divide.


How do you break down the prime factorization of 76?

You have to find the smallest prime number that can go into 76, which is 2 and find out what 76/2 is. The, you would have to take the non-prime number and find the smallest prime number that can go into that, and divide by those to numbers again. The prime number you had with 76, you would keep that and keep dividing the non-prime numbers until you end up with all prime numbers.


What would you prefer odd numbers or prime numbers?

Prime numbers.


How do you find prime numbers?

Prime numbers are the numbers that can only be divided by 1 and them selves. As in 13 if you were to factor it using only whole numbers you would see that its factors are only 1 and 13. There for it is prime. While 12 you see that the factors are 1,2,3,4,6,12 meaning that it is not prime.You test several numbers, to see whether they are prime numbers, until you find a prime number.


What is the GCF of 61 and 73 using factorizations?

61 and 73 are prime numbers. Prime numbers don't have prime factorizations, since their only prime factors are themselves. Since these would have to be different numbers, they don't have any prime factors in common. The GCF of any set of prime numbers is 1.


Are most prime numbers also odd numbers?

All prime numbers are odd numbers. If one were even, it would be divisible by two and would, therefore, not be prime.


How would you do prime factorization?

All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.

Is there any prime numbers that are square numbers?

No. By definition, the square root would be a factor so the number would not be a prime.


How do you divide three digit numbers?

You divide them the same way that you would using 1 or 2 numbers. It is just diving 3 numbers into a number instead of just using 1 or 2. It is that simple. It is just annoying having to manually doit though. I use a calculator now that I am out of school. Good luck.


Are all multiples of a prime numbers prime numbers?

no, because then they would be divisible by the number you multiplied it by.


Is there a remainder when you divide a prime number?

Yes, unless you divide the number by itself, then the answer would be one. Also, you can divide it by one, and the answer would be that number.


How do you find the mean using 16 numbers?

The mean is the average. You simply add all the numbers and divide by how many numbers there are. So the mean of 16 numbers would be the sum of all 16 numbers, divided by 16.


How do you calculate average using fractions?

In the same way as you would with numbers which are not fraction. Add together the fractions and divide by their count.


What are two prime numbers that if multiplied would generate a 400-digit number?

Any two prime numbers, of about 200 digits each, would work.Any two prime numbers, of about 200 digits each, would work.Any two prime numbers, of about 200 digits each, would work.Any two prime numbers, of about 200 digits each, would work.


What are the prime numbers between five and fifteen?

5,7,11,13 are prime I would suggest looking into the sieve of erasthenes for further reading. For tests, look at odd numbers and see if odd numbers divide them. ie 9 is not in the lsit because it is divisible by 3. Even numbers are always divisible by two.


Is sixty three a composite or prime number?

I would say composite cos it can't be prime. prime is no which can only divide to aone nd it self but 63 can divide by 3!!!!!!!!!


What is the difference between prime numbers and prime factor?

A prime number is any number which has only 2 factors. That is, a number that can divide only by itself and 1. For example, 29 is a prime number, as it cannot divide evenly by any number other than itself and 1. A factor of a number is any number which that original number can divide by evenly. For instance, 24 can divide by 8, so 8 is a factor of 24. However, 8 isn't prime so it isn't a prime factor of 24. The prime factors of 24 would be 2, 2, 2 and 3.


What is the definition of prime factorization?

The prime factors of a number by multiplying each other. You can also use exponents. a prime factorization is when you divide a number and see what all of the prime (odd) numbers make up that number. EX. 9 / \ 3 3 then you would circle the 3's because they are prime.


What is the least common multiple of prime numbers?

It depends on what the numbers are. For example, if the prime numbers you were talking about were 3 and 7, the least common multiple would be 21. If your numbers were 2 and 3, it would be 6.


What numbers would have less than two factors?

Prime numbers


Are there any prime numbers that are also square numbers?

i would say no


What 3 prime numbers have the sum of 3?

There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.


Is there an infinite amount of prime and composite numbers?

Because there are an infinite number of numbers, it would stand to reason that there are an infinite number of prime and composite numbers.
