To find the greatest common factor (GCF) of 18j and 27, we need to determine the highest power of each prime factor that appears in both numbers.
First, let's prime factorize 18j and 27.
18j: The prime factors of 18j are 2, 3, and j (where j represents a variable).
27: The prime factor of 27 is 3.
To find the GCF, we need to identify the highest power of 3 that appears in both numbers. Since 3 is a factor of 18j and 27, the GCF is 3.
Therefore, the GCF of 18j + 27 is 3.
Find the GCF of 18j+27 .
