## Related Questions The prime factorization for 24 is (2)(2)(2)(3). The prime factors of 24 are 2 and 3.  In prime numbers 19+5 = 24 or as a product of its prime factors 2*2*2*3 = 24 Because on the list of factors of 24, 2 and 3 are the only prime numbers. 24 is not a prime number because it has more than two factors. With the use of prime factorisation the numbers are: 18: 2,3,3 24: 2,2,2,3 The actual factors are for both 18 and 24 are 2 and 3 Two (or more) numbers are relatively prime if they do not have any factors in common. The numbers need not be prime numbers. Thus 24 and 35 are not prime numbers but they are relatively prime since 24 = 23*3 and 35 = 5*7 have no factors in common.  All non-zero numbers have factors. Some factors are prime numbers. Prime factors are factors that are prime numbers. The prime numbers (factors) of 400 are: 2 and 5 All numbers have factors. Some factors are prime numbers. These are prime factors. A factor string where all the factors are prime numbers is called a prime factorization. Any prime number only has two factors: one and the number itself. Since 12 is a factor of 24, all of its factors, prime or otherwise, are common. 13 + 11 Prime numbers are numbers only have 2 factors - 1, and itself. All numbers have factors. Some factors are prime numbers. These are known as prime factors. All numbers have factors. Some factors are prime numbers. These are known as prime factors.  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.  All numbers have factors. Some factors are prime numbers. These are called prime factors. All numbers have factors. Some factors are prime numbers. These are known as prime factors. Prime factors of numbers are small numbers that the bigger (original) number can divide by. The prime factors have to be prime. This means they only have two factors, itself and one. Prime factors are factors that are also prime numbers. The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24 All numbers have factors. Some factors are prime numbers. We call these numbers prime factors. 3 is a prime factor of 12.
