The only number equal to 84 is 84,and it isn't a prime number.The prime factors of 84 are: 1, 2, 2, 3, and 7 156 is a not a prime number. A prime number is a number that only can divided by 1 and itself. Examples of Primes is 1, 2,3, 5, 7, 11, 13, 17.......................... 156 factors include 1,2,3,4,6,12,13,26,39,52,78,156.

The prime factors of 84 are 22 x 3 x 7. No. The only even prime number is 2.  84 is a composite number because it has more the 2 factors    The greatest common factor of the numbers 84, 120 and 156 is 12. 84 is a composite number.Its factors are 1,2,3,4,6,7,12,14,21,28,42,and 84All even numbers greater than 2 are composite. The greatest common factor of 84 132 and 156 is 12.  If two prime number have a sum of 54 they cannot have a sum of 84, and conversely. The prime factorization of 156 is 2x2x3x13. In other words, the prime factors of 156 are 22, 3 and 13. Hope I helped you! :)
