finde the gcf of 18j+27

To find the greatest common factor (GCF) of 18j and 27, we need to determine the prime factors of each number and then find the common factors.

The prime factorization of 18j is 2 * 3^2 * j.

The prime factorization of 27 is 3^3.

To find the common factors, we compare the prime factors of both numbers:

The common factors are 3^2 and j.

Therefore, the GCF of 18j and 27 is 3^2 multiplied by j, which is equal to 9j.
