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.
2 and 3 are prime numbers that are factors of 12. There is an infinite list of prime numbers that aren't.
it means to find out if the number is composite or prime
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor. 3 is a prime number. 3 is a factor of 9. 3 is a factor of 12. 3 is a common prime factor of 9 and 12.
Two and three.
Oh honey, let's break it down for you. The factors of 12 are 1, 2, 3, 4, 6, and 12 because they can all divide evenly into 12. Now, the prime factors of 12 are 2 and 3, because those are the prime numbers that multiply together to give you 12. So, there you have it, sweetie!
The products of a square of a prime and a prime, like 12.
The factors of 12 are 1, 2, 3, 4, 6, 12 Of these, 2 and 3 are the only prime numbers.
The prime factorization of 12 is: 2 x 6 2 x 2 x 3. The prime numbers that are factors of 12 are 2 and 3.
All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. The factors of 12 are 1, 2, 3, 4, 6, 12 Since 4, 6 and 12 are composite numbers, they are the composite factors of 12.
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.
To find the prime factors all you need to do is find all factors, and identify which ones are prime numbers. 12=1*12=2*6=3*4 factors=1,2,3,4,6,12 Prime numbers can only be divided by 1 and the number itself. Thus the prime factors of 12 are 2 and 3 (1 is, by definition, not prime (i'm not exactly sure how to explain why))
