31- not divisable by 3 (3 x 11= 33), 4 (4 x 9= 36), 5 (doesn't end in 5 or 0) or 2 (last # not even)
oh, 17 works too... and probably a ton of other numbers.
12 is the smallest multiple of 3 and 4.

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.
60
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.

A number that is divisible by 2, 3, 4, 5, and 10 must be divisible by the least common multiple of these numbers, which is 60. Therefore, any number that is a multiple of 60 will be divisible by 2, 3, 4, 5, and 10. This is because 60 is the smallest number that contains all the prime factors of 2, 3, 4, 5, and 10.
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.
Any multiple of 60.
