Question

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

Answer 1

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. 

Answer 2

36 because the rest are prime #'8
