Is 140 a composite number and why?
140=2x2x5x7, 140 is a composite. all even numbers above 2 are composite composite. because they can be divided by more than just 1 and themselves. 140/2 = 70 140/4 = 35 140/5 = 28 140/10 = 14
Is 140 prime or composite?
140 is a 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.
What are the crossed out numbers above one called on a sieve of Eratosthenes?
composite numbers
Is 140 a prime or composite or neither?
It is composite.
Is 140 a composite number or prime?
140 is a composite number because it is an even number greater than 2.

Is 140 a prime or not?
No. All whole numbers ending in zero are composite.

Is 140 a composite or prime?
Composite. All positive, whole numbers greater than two and ending in 0, 2, 4, 6 or 8 are composite.
What are the crossed out numbers above one called on a sieve of Eratosthenes?
composite numbers
Is 140 a prime or composite or neither?
It is composite.
How many composite numbers are there from 125 to 140?
They are the numbers that have more than two factors because prime numbers have only two factors which are themselves and one.
Is 140 a composite number or prime?
140 is a composite number because it is an even number greater than 2.
140 prime or composite?
That is easy, 140 is prime.
Is 140 prime composite or unit?
140 is a composite number because it has more than two factors
Is there more prime numbers then composite numbers?
There are many, many more composite numbers than prime numbers. For example, beyond the number 3, every other number is composite, as it is divisible by 2. Following this, every number ending with a 5 other than 5 itself is composite, as it is divisible by 5, and every third odd number is divisble by 3. There are many complicated divisibility tests for numbers above 5.
Are composite numbers even numbers?
Not all composite numbers are even, but all even numbers except 2 are composite.
