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

LCM = 168
The mass number is the sum of protons and neutrons in an atom. Since magnesium has 12 protons, a magnesium atom with 14 neutrons would have a mass number of 26 (12 protons + 14 neutrons = 26 mass number).
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.
No. They have different masses, but the same atomic number. Carbon-12 has a mass number of 12 and atomic number of 6, and carbon-14 has a mass number of 14 and atomic number of 6. The difference in mass number is due to different numbers of neutrons. Carbon-12 atoms have 6 neutrons and carbon-14 atoms have 8 neutrons.
