How can you determine if a number is prime by looking at the factors of the number?
A prime number only has two factors. If the number you're looking at has more than two factors, it is not prime.
How do you determine if a number has 3 factors?
Squares of prime numbers have three factors.
How do you determine the prime factorization of numbers?
Keep dividing until all the factors are prime.
Does 38 have a odd number of different factors?
The factors of 38 are 1, 2, 19, and 38. There are four different factors. The prime factors of 38 are 2 and 19. There are two different prime factors.
Determine if 23 is prime or composite?

What is the LCM of 28 and 21?
To determine the least common multiple of two numbers, determine the prime factors of both number. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor). The prime factors of 21 are 3 and 7. The prime factors of 28 are 2, 2, and 7. The prime factors in common are a single 7. Therefore, the lowest common multiple is 21 x 28 ÷ 7 = 84
How can you determine whether the gcf of two numbers is one by looking at their prime factorizations?
If there are no prime factors in common, the GCF is 1.
How do you determine all factors Prime factorization?
A prime number has only 2 factors which are itself and one whereas a composite number has more than two factors.
What are distinct prime factors?
Distinct prime factors are the prime factors that are distinct (or different) from each other. A list of distinct prime factors is a list of one of each different prime number that is a factor. For example, the prime factors of 8 are 2, 2, and 2. The only distinct prime factor is 2, which occurs multiple times.
