The lowest common multiple of 3 and 8 is 24.List the multiples of 3 and 8. The lowest multiple they have in common is the least common multiple.3: 3, 6, 9, 12, 15, 18, 21, 24, 27...8: 8, 16, 24...
multiples for 3: 3, 6, 9, 12, 15, 18, 21, 24 multiples for 8: 8, 16, 24 The least common multiple is 24
lcm(8, 9, 24) = 72 Using prime factorisation: 8 = 2³ 9 = 3² 24 = 2³ x 3 lcm = 2³ x 3² = 72
The LCM of 12 and 24 is 24.

The Least Common Multiple (LCM) for 2 9 24 is 72.
3 6 9 12 15 18 21 24 etc. A number is divisible by 3 if the sum of its digits are a multiple of 3. For example: 684. Add the digits and you get 18, which is a multiple of 3 (if you're not sure then add 1+8 = 9, which is a multiple of 3. If you repeat the summing of digits, eventually you will get to a single digit number: if it's 3,6 or 9, then it's a multiple of 3. Additionally, if it is 9, then it's a multiple of 9, as well.
If you divide 24 by 9, you do not get a whole number answer.
