All numbers have factors. Some factors are prime numbers. These are known as prime factors. Some numbers have some of the same prime factors as other numbers. These are known as common prime factors. 3 is a common prime factor of 12 and 15.
That's pretty self-explanatory. Prime numbers can be factors of other numbers. 2 and 3 are prime factors of 6.
None of the prime numbers have any factors other than themselves and 1.
Numbers can't have prime numbers, some numbers are prime numbers. Prime numbers are numbers that have no factors other than 1 and itself. 85 is not a prime number because its factors are 1, 5, 17, and 85.
No. Prime factors are the numbers that make up other numbers, but they have to be prime. Prime factorisation is the process of finding the prime numbers that create a number. This is when you multiply the prime numbers together and the product is the original number. For example: 20 5x4 5x2x2 This process is called prime factorisation. In this case, the prime numbers are 2, 2, and 5.
The relationship between prime numbers and composite numbers is that they are antonyms or opposites of each other. A natural number, is either prime or composite, but it can not be both. Prime numbers have only two factors, one and itself. Composite numbers are whole numbers that are not prime numbers, which means that they have factors other than one and itself.
The prime numbers.
No 9 is not prime. It's factors are 1,3,9. Proper factors: 1,3. Factors are numbers that are multiplied with other numbers to get a product. Proper factors are factors of a number except for itself. No 9 is not prime. It's factors are 1,3,9. Proper factors: 1,3. Factors are numbers that are multiplied with other numbers to get a product. Proper factors are factors of a number except for itself. Composite numbers are numbers with more than 2 factors and more than 1 proper factor. Prime is the opposite of composite.
Prime numbers have only two factors whereas composite numbers have more than two factors and that 1 is not considered to be a prime or composite number but it is a factor of all other numbers.
Example: What are the common prime factors of 120 and 252?Find the prime factorization of each number by breaking it down into the lowest possible numbers that can be multiplied together to make the original number.120 = 2x60 = 2x2x30 = 2x2x2x15 = 2x2x2x3x5252 = 2x126 = 2x2x63 = 2x2x3x21 = 2x2x3x3x7Notice that there are 2 2's and a 3 in each factorization: the common prime factors are 2, 2, and 3.
