At least two factors because prime numbers have two factors and composite numbers have more than two factors.
All composite numbers have more than 2 factors whereas prime numbers have only 2 factors
It is: the 'least common denominator'
Yes. To be composite, the first number has at least 2 prime factors, the second number also has at least prime factors; the product of the two will have at least 4 prime factors, so it must be a composite number.
At least three
It must have at least 3 factors.
A composite number is a number that has at least 3 factors. (It can be evenly divided by at least 3 number.) 25 has 3 factors: 1, 5, and 25.
45 is a composite number. A number is composite if it can be evenly divided by and least 3 numbers (if it has at least 3 factors). Any composite number has at least one factor other than one and itself. 45 has 6 factors: 1, 3, 5, 9, 15, and 45.
No, prime numbers have only two factors: 1 and itself. Composite numbers have at least 3 factors.
Yes, a composite number has to have at least one factor other than 1 and itself, so they have to have at least 3 factors.
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.
A prime number has exactly 2 factors. A composite number must have at least 3 factors. 1 does not fall into either of the above definitions so it is not composite. It used to be considered a prime number but is not any longer.
A composite number is a number that has additional factors besides ' 1 ' and itself. The number ' 1 ' has no additional factors besides ' 1 ' and itself. So it's not a composite number.
