I assume you mean LCM, least common multiple. The least common multiple of 3 and 4 is 12. 12 is a multiple of 3. 12 is a multiple of 4. No smaller number is a multiple of both 3 and 4.
The least common multiple of 2, 3 and 4 is 12.
The smallest multiple of 2,3,4, and 5 is 60 ■
Multiply the number by 1, 2, 3, 4 and so on.
A number that ends in 3 can't be a multiple of 4 because the 4 times table goes in a pattern, (e.g 4, 8, 12, 16, 20, 24.) If the number ends in either 0 2 4 6 8 then it couldbe a possible multiple of 4. It always ends in an even number. 3 is not an even number so it is not going to be the last number of a multiple of 4.
To find the least common multiple of 2, 3, and 4, factor them: 2 = 2 x 1 3 = 3 x 1 4 = 2 x 2 (Since one 2 has already been used to factor the number 2, only one 2 counts in the factors for the number 4.) The least common multiple of 2, 3, and 4 = 1 x 2 x 3 x 2 = 12.

The number you're looking for is 4. It's an even number, and when you add 5 to it, the result is 9, which is a multiple of 3.

12 is the smallest multiple of 3 and 4.
If a number is divisible by 4, it also means that the same number is divisible by 2. But if the number ends in a 3, it can't be divisible by 2 and, to a further extent, can't be divisible by 4.
To find the least common multiple (LCM), first factor each of the numbers. The factors of 4 are 2*2. The factors of 9 are 3*3. List the factors of the first number, 4, which is 2*2. List all factors from the second number that are not included in the first number, which is 3*3. The LCM is 2*2*3*3 or the original numbers 4*9 = 36. The LCM of 4 & 9 is 36.
