Im so confused with these questions:

which of the following numbers are composite?
0,1,15,19,23,31,49,55,59,87,91,97,103,105

A. 1,23,31,59,91
B. 15,49,55,87,91,105
c. 0,1,19,23,31,105

• Basic Math -

composite means that the # can be divided by one and it's self. so that means the anser is B

• Basic Math -

that is the definition of a PRIME number..a composite number is a number that can be divided by factors other than 1 and itself!! the correct answer is B...try using divisibility rules...105 gives it away because that number can be divided by 5 so it is automatically not a prime
