2 factors, but a Prime number has only two factors (itself and one).
Note that 1 is not considered to be a prime number.
At least two factors because prime numbers have two factors and composite numbers have more than two factors.
No.
In number theory, the fundamental theorem of arithmetic, also called the unique factorization theorem or the unique-prime-factorization theorem, states that every integergreater than 1 either is prime itself or is the product of prime numbers, and that this product is unique, up to the order of the factors.
In the context of primes and factoriation, every counting number is a factor.
No, prime numbers do not have proper factors.
Not with negative numbers. -10 is a multiple of -2.
Every number greater than 1 has the two factors 1 and the number itself.
No. They have different number of factors
Exactly.
Every number greater than 1 has 1 and the number itself as factors. If it has no other factors besides these two factors, it is a prime number. If it has more factors than 1 and itself, it is a composite number.
No.
' 1 ' and itself.
Every positive integer greater than 1.
Every positive integer greater than 1 can be expressed as the product of a unique set of prime factors. The count of these factors is the prime factors number for the number.
Given an arbitrary odd natural number greater than five, x, let y = x - 3, then y is an even number greater than 2. By assumption we have that y is the sum of two primes, say y1 and y2, but then x = y1 + y2 + 3 (which is the sum of three primes).
No because natural numbers are positive whole numbers greater than 0
Every number has at least one factor, the number 1.Every number greater than 1 has at least two factors, 1 and itself.Any number with exactly 2 factors is prime.Any number with more than 2 factors is composite; in this case it can be factorised completely into primes.The number 1 has only one factor. It is therefore neither prime nor composite.
Yes, every natural number is a whole number.
