Differentiate prime numbers and composite numbers?
A prime number is a whole number that has only two distinct factors: 1 and the number itself. A composite number has at least three distinct factors.
What is the least natural number that has four distinct prime factors?
...I keep finding the same questions that are on geometry extra credit.. the exact same questions. O_o
Which of these numbers when given in their prime factorization form has the least number of distinct prime factors 80 100 144 289 441?
289 does.
Do all even numbers have at least two prime factors?
Not two DISTINCT prime factors, no. For example, 64 = 2^6 only has prime factor 2. All even numbers which are not a power of 2 must have at least two distinct prime factors, however; one of them will, of course, be 2.
What is the least natural number divisible by each natural number less than or equal to twelve?
It is 27720.
What is the least natural number that has exactly 4 distinct odd factors?
3*5*7*9 = 945 ...check if any number less than that has exactly four distinct factors.
What is the least number that has eight distinct factors?
24

How many factors does every natural number greater then 1 had at least?
2 factors, but a prime number has only two factors (itself and one). Note that 1 is not considered to be a prime number.
Which of these numbers when given in their prime factorization form has the least number of distinct prime factors 80 100 144 289 441?
289 does.
Least natural number?
Least or smallest natural number is 1.
Each composite number has a least blank factors?
at least three factors.
Do all even numbers have at least two prime factors?
Not two DISTINCT prime factors, no. For example, 64 = 2^6 only has prime factor 2. All even numbers which are not a power of 2 must have at least two distinct prime factors, however; one of them will, of course, be 2.
What is the least common multiple of 33 and 8?
the answer is 264 Prime Factorizations 33=3*11 (2 distinct prime factors) 8=23 (3 prime factors, 1 distinct)
Why does 2x3x4x5 give you the least number of factors?
It does not! The number 7 has fewer factors!
What is the least number that has 4 different prime factors?
Logically, the smallest number with 4 different prime factors would have to be the product of the smallest four prime numbers. So the smallest natural number with four different prime factors is 210 (2*3*5*7).
