What else can I help you with?
Can all odd numbers greater than 1 but less than 10 are prime numbers?
No, says the number 9.
Julia says that prime numbers have to be odd and composite numbers have to be even. is she correct explain how you know?
Julia is incorrect. 2 is an even prime number and 9 is an odd composite number.
What is 1 true statement about factors?
A great statement to make here would be one about prime factors, and it is the Fundamental Theorem of Arithmetic."Every positive whole number can be written as a unique product of primes."This sentence says that if a number is not a prime, it is the result of multiplying primes together.It says that numbers have only one way of being broken up into prime factors.It says that the number 1 is not a prime number, but is instead called an empty product.It says that Mathematics works.
Who is the founder of prime numbers?
Eratosthenes, It says it is Eratosthenes.
Is 2 232 a prime number?
This is a simple, yet accurate definition of a prime number: "an integer that has no integral factors but itself and 1." The number 2 only has two integral factors: 1 & 2. Since the definition says it must have no factors besides 1 and itself (2), the number 2 must be prime.
Why is 21 a prime number?
Who says it is? 21 is a composite number!
Is 429 prime?
No 429 is not prime. A prime number is a number where the only multiples of it are "1" and the number itself. 429 / 3 = 143. So 3 x 143 are also factors.Prime numbers do not end in 0,2,4,5,6,8; excluding 2 (Two), 22 is not prime but 2 is because 1 x 2 = 2. And remember the definition says a prime number is a number that can only be multiplied by 1 and itself.
What is the prime factorization of 190?
A famous theorem says that each number has a unique prime factorization.You can begin by expanding the number to known products, say 10 * 19 (or 5*38 or ...)You just keep going until only prime numbers remain. Here, 19 is prime but 10 is composite so we reduce it further to 2*5. Both of these are prime numbers, so we are done.The resulting pf is 190=2*5*19 (only powers of prime numbers on the right)It is: 2*5*19 = 190
What is the smallest number which is exactly divisible by all the numbers from 1-10?

Why is is important that 1 is not a prime number?
It important that 1 is not prime because a quote says: "A prime number is a natural number that has exactly two different natural number factors. and so i say 1 is not a prime because a prime number has 2 factor 1 and it self and 1 dose not.
