To find the Greatest Common Factor (GCF) of 20, 30, and 90, you first need to factor each number into its prime factors. The prime factorization of 20 is 2^2 * 5, of 30 is 2 * 3 * 5, and of 90 is 2 * 3^2 * 5. Then, you identify the common prime factors among the numbers, which are 2 and 5. Finally, you multiply these common prime factors together to find the GCF, which is 2 * 5 = 10.
