Just use: if number % 12 == 0:

This is because 12 is the least common multiple of 4, 3, and 2.

On Edit:

Here is some code to compute the least common multiple of a list (or other iterable) of integers:

from math import gcd

def pair_lcm(a,b):
    return a*b//gcd(a,b)

def lcm(nums):
    """computes the lcm of iterable nums"""
    m = 1
    for num in nums:
        m = pair_lcm(m,num)
    return m

For example,

>>> lcm(range(1,11))
2520

if you don't want to do the math to combine them:

for number in range(100):
    if all(number % n == 0 for n in (2, 3, 4)):
