## Can prime numbers have a GCF?

Since 1 is a factor of every number, any two or more numbers have a GCF, because even if the numbers are prime, or if they don’t share any prime factors, then the GCF will be 1. If they do share any prime factors, then the GCF will be the product of those shared prime factors.

**Is the product of two prime numbers prime or composite?**

Answer: Prime numbers has only two factors 0&1. Composite numbers have more than two factors. The can be expressed as a product of primes.So,it is obviously correct that the product of two prime numbers is a composite number for example,2 and 3 are two prime numbers.

### What factors do prime and composite numbers have in common?

A prime number has only two factors: 1 and itself. A composite number has more than two factors….Definitions.

factors of 10: | 1 x 10, 2 x 5 | 10 is composite |
---|---|---|

factors of 11: | 1 x 11 | 11 is prime |

factors of 12: | 1 x 12, 2 x 6, 3 x 4 | 12 is composite |

factors of 13: | 1 x 13 | 13 is prime |

factors of 14: | 1 x 14, 2 x 7 | 14 is composite |

**What is a prime number always greater than?**

Primes are always greater than 1 and they’re only divisible by 1 and themselves. They cannot be made by multiplying two other whole numbers that are not 1 or the number itself. Prime numbers include: 2,3,5,7,11,13,17,19… and so on. Any number that is not prime is called a composite number.

#### What’s the GCF of two prime numbers?

1

Statement 1: The greatest common factor of any two distinct prime numbers is 1.

**How many factors does the product of two prime numbers have?**

The product of two distinct prime numbers has four factors: itself, the two prime numbers and 1.

## Do prime numbers only have 2 factors?

Prime numbers are numbers that have only 2 factors: 1 and themselves. For example, the first 5 prime numbers are 2, 3, 5, 7, and 11. By contrast, numbers with more than 2 factors are call composite numbers.

**Is a composite number even?**

All even number except 2 are composite numbers.

### Is the number 1 a prime or composite number?

The number 1 is neither prime nor composite. The prime numbers between 2 and 31 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 and 31 since each of these numbers has only two factors, itself and 1.

**What’s the difference between GCF and LCM in math?**

While GCF is the calculation of the highest integer that divides a number into two or more equal parts, LCM refers to the common multiple of the lowest value shared by the given numbers. The full-form of each is also different. While GCF stands for Greatest Common Factor, LCM is the abbreviation used for the Least Common Multiple.

#### Which is the greatest factor of a given number?

Greatest Common Factor or GCF is the greatest whole number that divides a given number into two or more equal halves. Factors are numerical digits which when multiplied result in the given number. A common factor is a factor that is mutually shared by a given set of numbers.
