no. it is not a prime number. a prime number is a number greater than 1 that is only divisible by 1 and itself. Example of a prime number is 2. 2 / 2 = 1 or  2/ 1 = 2. 1212 can be divided by 2, 3, 4, 6,.... It is not a prime number. Instead it is recognized as a composite number. 

1,212 is NOT a prime number. If 1,212 were a prime number, 1,212 would only have two factors, which are 1 and itself. Since 1,212 has another factor other than 1 and itself (which is 2), 1,212 is not a prime number. Hope this helps~
