Prime Factorization## hi

would you plz help me with this

If K is an integer and 2 < k < 8, what is the value of k?

1) k is a factor of 30

2) k is a factor of 12.

my answer was c

the prime factorization for 30 is 2-3-5

for 12 is 2-2-3

so just 3 between them so it is c

what is the wrong here?

## Be careful, the question does

Be careful. The question does not say that "k is a PRIME factor of 30." It just says "k is a factor of 30."

Statement 1: The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30.

Since we're told that 2 < k < 8, we can conclude that k = 3, 5 or 6

INSUFFICIENT

Statement 2: The factors of 12 are: 1, 2, 3, 4, 6, 12.

Since we're told that 2 < k < 8, we can conclude that k = 3, 4 or 6

INSUFFICIENT

The two statements COMBINED

Statement 1 tells us that k = 3, 5 or 6

Statement 2 tells us that k = 3, 4 or 6

Since both statements must be true, we can see that k can still equal 3 or 6.

INSUFFICIENT

Answer: E
