How to find the GCF and LCM, the main factor, and the sum of all the factors of ....?
So I started school today and I'm in the honors in mathematics. My first year, so I do not know much. Help / teach me (not had time to ask the teacher and their future because ...) explain to each you how he did find the GCF and LCM of 2 and 4, we find the sum of all factors that are smaller than the number given 8 to find the factor of 12 greater premium put the i made it, I'm putting them to see if I am entitled to do and how it. Thanks so much! And next time I will ask the teacher, but this was the first day and yes ... thanks!
GCF - compare the factors of 2 and 4: 2 to 1, 2 4 - 1, 2, 4 the GCF is 2 because it is the most important factor that both figures have LCM - the same, but with multiples: 2 to 2, 4, 6, ... 4 to 4, 8, 12, ... the MCL is 4, since it is the smallest multiple that two numbers have to find the sum of all factors necessary to find the prime factors. So, with 8, you have 1, 2, 4, 8, but since 8 is not less than 8, do not add that. so that 1 +2 +4 = 7. the prime factorization of 12 is 2x2x3. 3 is the biggest number. SO 3 is the greatest prime factor of 12. Hope this helps!
