Is the number 40 a prime number?
NO it is divisible by more than two numbers
What number is divisible by the most numbers?
There can be no such number. Suppose n is a number that is divisible by k numbers. Suppose p is any integer greater than 1. Then n*p is a number that is divisible by at least k+2 numbers.In this way it is always possible to find another number that is divisible by more numbers.
Is every composite number divisible by 2?
No, composite numbers are the numbers having more than three factors
What are all the composite numbers and what are they divisible by?
Composite numbers are the non-prime numbers, numbers that have more than two factors. Every number that is not prime (has factors other than one and itself) is a composite number. A composite number is divisible by some number other than one and itself. For example, the number 6 is a composite number because it is divisible by 2 and 3 (in addition to 1 and 6) while the number 7 is prime because it is not divisible by any number other than 1 and 7.
