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.

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.
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
