Which number is a composite number 7 11 31 or 36 show your work.

Alrighty, so if I remember correctly a prime number is a number in which the number 1 and a number are the only factors of said number and a composite number has more than 1 and itself. 7: 7, 1 11: 11, 1 31: 31, 1 36: 1,2,3,4,6,9,12, ... 36. Therefore 36 is composite.

36 because the rest are prime #'8
