12:12,24,36,48,60,72,84,96,108,120 14:14,28,32,46,60,74,88,102,116,130 16:16,32,48,64,80,96,112,128,144,160
2 goes into 12 6 times and into 14 7 times Two go's into both numbers. As 2x6=12 and 2x7=14.
26 here is why: on the number line the distance between 14 and 8 is 6, so we need a number whose distance between 14 and that number is 12.. so 12+14=26 and that works
168 ÷ 14 = 12
168 ÷ 14 = 12
12:12,24,36,48,60,72,84,96,108,120 14:14,28,32,46,60,74,88,102,116,130 16:16,32,48,64,80,96,112,128,144,160
2 is a common factor
Their LCM is 924

The mass number is the number of protons plus neutrons. Magnesium is element number 12, so it has 12 protons. Its mass number with 14 neutrons is 12 + 14 which is 26.
LCM = 168
The LCM of 12 and 14 is 84
ANSWER: The next composite number after 12 is 14.
12: 1 2 3 4 6 7 12 14 21 28 42 84.
26 here is why: on the number line the distance between 14 and 8 is 6, so we need a number whose distance between 14 and that number is 12.. so 12+14=26 and that works
Any number of the form 84*k, where k is an integer, is evenly divisible.
