Question: what is the GCF (greatest common factor )of 12 and 18
WebIf so, you compare the list of Factors of 12 with the list of Factors of 18 to find the largest number they have in common. As you can see from the lists above, the greatest … WebGreatest common factor (GCF) of 18 and 12 is 6. GCF (18,12) = 6 We will now calculate the prime factors of 18 and 12, than find the greatest common factor (greatest … WebLet's say you want to calculate the GCD and LCM of two numbers: 12 and 28. First, determine the prime factorizations of 12 = 2 × 2 × 3 and 28 = 2 × 2 × 7. The GCD is the string that is present in both sets of factorizations, i.e., 2 × 2 = 4. The LCM is the greatest power of all exponents; i.e., 2 × 2 × 3 × 7 = 84. diameter of planets in order
