To find the LCM of three numbers, you would start by splitting them into their prime factors. In this case, the three numbers already are prime. The next step would be to eradicate any duplicate factors. In this case, there are none. Thus, all we have to do is multiply the primes, 3, 5 and 7 together. This gives us:

3x5x7 = 105

So the LCM of 3 5 and 7 is 105
