H CF and LCM of 12 and 30? - Answers

To find HCF & LCM of two or more numbers. Divide by prime numbers. We note in this case, 12, & 30 are both even numbers, so they will divide by '2'. Hence 2)12 2)6 3)3 = 1 & 2)30 3)15 5)5 = 1 First reduce both numberx to '1'. Second;ly, we note that '2' & '3' bo appear in each set of numbers. Hence 2 x 3 = 6 is the HCF Having made this multiplication we are left with a '2' in the twelve and a '5' in the thirty.. Hence 6(HCF) X 2 X 5 = 60 the LCM. Done!!!! Hope that helps!!!!
