Is the number 770 a prime number or composite?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 770 is composite.
Is 159 prime or composite number?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 159 is composite.
Is the number 47 composite or prime?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 47 is prime.
Is every number in the 90s a composite number?
Assume you want to know if every number between 1 and 90 is a composite number.
No, not every number between 1 and 90. Take 2 for instance. Then, 2 is prime since the factors of 2 are 1 and itself!

Assumed wrong!
In the 90s refers to 90-99, but the answer is correct, because 97 is a prime.
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 342 is composite.
Is 14986982 a prime or composite number?
It is a composite number because it has more than two factors
What is the greatest 2-digit composite number?
The greatest two-digit composite number would be 99, since 99 can be divided by 11, 9, and 3. I you look around this number, you will see why: 98 is also a composite number, but it is smaller than 99. 100 is also a composite number, but it has three digits. 97 has two digits, but it is a prime number. On the other hand, 99 divided by 11= 9, 99 divided by 9= 11, and 99 divided by 3=33.
What Two Numbers are between 40 and 50?
There are an excessive amount of numbers between 40 and 50. Depending on what numbers are defined, you might end up with two numbers (x, y) like 41 and 43, which are both between 40 and 50. But you might as well choose 45 and 49, or 40,123 and 49,987, which are also "Two Numbers between 40 and 50".
Answer:
x =/= y
x = ]40, 50[ , x = R
y = ]40, 50[ , y = R
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. Pi is neither.
Do composite numbers have to have three 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.
