What is the gcf of 36 60 and 135?
To find the greatest common factor (GCF) of 36, 60, and 135, we first need to factorize each number. The prime factorization of 36 is 2^2 * 3^2, the prime factorization of 60 is 2^2 * 3 * 5, and the prime factorization of 135 is 3^3 * 5. To find the GCF, we identify the common prime factors and take the lowest power of each common factor. Therefore, the GCF of 36, 60, and 135 is 3.
